List Different Types Of Environments Geographic And Man-made Environment


Beneath the lithosphere lies the mantle which is heated by the decay of radioactive elements. The mantle though solid is in a state of rheic convection. This convection process causes environment consists of the lithospheric plates to move, albeit slowly. Volcanoes result primarily from the melting of subducted crust material or of rising mantle at mid-ocean ridges and mantle plumes.

  1. Air also contains a variable amount of water vapor and suspensions of water droplets and ice crystals seen as clouds.
  2. They include weather conditions; the wearing away, or erosion, of rocks and soil; and natural disasters such as earthquakes.
  3. When a prey organism avoids a predator, it has higher fitness than members of the same species that were killed by the predator.
  4. Food chains are generally simpler than what really happens in nature.

The destruction of forests leads to destroying the ecosystem as a whole. The Biosphere is that part of Lithosphere, Hydrosphere and Atmosphere where life exists. It consists of the domain of living organisms where they interact with each other in the physical environment of the lithosphere, hydrosphere, and atmosphere. The environment infers to all living and non-living beings in their physical and biological surrounding that affect an organism during its lifetime.

Freshwater ecosystem is comprised of four major constituents, namely elements and compounds, plants, consumers, and decomposers. Read this tutorial to learn about each of them and their role in a freshwater ecosystem… There are many environmental factors that arise due to the usage of water in one way or another and for every action that man does, there is a resultant effect on the ecosystem. In this tutorial, some scenarios where human action results in a response from the ecosystem, either physically or chemically, are described. Weather is a set of all the phenomena occurring in a given atmospheric area at a given time.[26] Most weather phenomena occur in the troposphere,[27][28] just below the stratosphere. A river is a natural watercourse,[7] usually freshwater, flowing toward an ocean, a lake, a sea or another river.

Grammar Terms You Used to Know, But Forgot

For example, the water moves continuously in the water cycle through different parts of the Earth in different forms such as liquid, ice, or vapor in various places. Although water moves continuously in this cycle, its balance remains constant over time. Similarly, the carbon and oxygen cycle maintain the balance of oxygen and carbon on Earth to maintain the life and the atmosphere of Earth. The biotic components represent all living things on Earth, such as bacteria, protists, algae, fungi, plants, and animals.

A hot spring is a spring with water temperatures that are higher relative to its surroundings. The water that is coming out of the spring is heated geothermally, https://1investing.in/ i.e. via the heat from the earth’s mantle. Because of the high temperature, it is one of the ecosystems that contain very few types of organisms.

They are the density-dependent factors and the density-independent factors. Find out the differences between the two in this tutorial. Know how these factors affect populations in an ecosystem… Decomposers are the last group of organisms through which energy flows through.

This tutorial investigates the genetic diversity in more detail. It also delineates how certain alleles are favored over other alleles in natural selection… Let’s take a look at the following ways to group or classify environments.

Sunlight is critical in aquatic habitats, because it provides the energy needed for photosynthesis. Living organisms have adapted to living in a particular environment with its specific conditions, such as humidity, temperature, light, and so on. Therefore, living organisms have to adapt and modify through time to survive and tolerate different environmental conditions. For example, oxygen eventually became incorporated into the Earth’s atmosphere after being released by photosynthetic organisms (such as algae) when producing sugar as food. Oxygen, eventually, became indispensable to the thriving of aerobic organisms, such as animals, including humans. The physical component refers to the non-living part of the environment.

PredationPredation is a relationship in which members of one species (the predator) consume members of other species (the prey). The lions and cape buffalo in Figure 2.13 are classic examples of predators and prey. In addition to the lions, there is another predator in this figure. Like the lion, itconsumes prey species, in this case species of grasses. Predator-prey relationships account for most energy transfers in food chains and webs.

The habitat is the physical environment in which a species lives and to which it is adapted. A habitat’s features are determined mainly by abiotic factors such as temperature and rainfall. These factors also influence the traits of the organisms that live there. Mammals that live in the habitat must have insulation to help them stay warm.

A related term “environ” is defined as “to surround” or “to enclose”. The scope of the environment varies — from the tiniest, “micro” scale to the largest, global scale. As for the abiotic factor, they can regulate the size or the density of a species population. Plants, for instance, have chloroplasts that enable them to harvest light energy. Then, they take carbon dioxide and water from their environment to convert them into sugar, a biomolecule that can be used to synthesize chemical energy (such as ATP). Because they are capable of producing their own food through photosynthesis, they are referred to as the producers.

In commensalism, one animal typically uses another for a purpose other than food. For example, mites attach themselves to larger flying insects to get a “free ride,” and hermit crabs use the shells of dead snails for shelter. An example is the human species and some of the species of bacteria that live inside humans. Through natural selection, many species of bacteria have evolved the ability to live inside the human body without harming it. Food ChainsA food chain represents a single pathway through which energy and matter flow through an ecosystem.

Species interactions are important biotic factors in ecologicalsystems. The focus of study of species interactions is the community. Energy enters ecosystems in the form of sunlight or chemical compounds. Changes in the environment therefore affect living things. They include weather conditions; the wearing away, or erosion, of rocks and soil; and natural disasters such as earthquakes. Weather occurs due to density (temperature and moisture) differences between one place and another.

The degradation of ecosystems and the changes in the global climate has resulted in the initiation of environmental ethics. Environmental ethics outlines the moral responsibilities of human beings and their respect towards the environment. Carbon dioxide is one of the major gas responsible for global warming. The forest trees play an important role in blocking the winds and prevent soil erosion. They are also responsible for the rainfall patterns in the area and subsequently recharge groundwater.

It includes the air we breathe, the water we use for our needs, the soil we cultivate, flora and fauna. In other words, the environment is collectively the total of water, air and land interrelationships among themselves and also with the human being and other living organisms. Ecosystems are responsible for the cycling of nutrients and for allowing the flow of energy, such as from the sun to the biotic components.

The pioneer species, like lichens and moss, will grow on the rocks and will become the pioneer species. Then, the site is next colonized by grasses and herbaceous plants. Soon, trees will grow on this site when their seeds reach the site, for example by wind currents or by bird droppings containing undigested seeds. Grassland ecosystems are typically found in tropical or temperate regions.
