Razi Brown A biological community of organisms and their environment is called an ecosystem. All of the organisms in an ecosystem are dependent on biotic as well as abiotic factors for energy and nutrition. Interdependence in nature is illustrated by the transfer of energy within an ecosystem. There are two major types of ecosystems: …
All areas of earth where life exists are called the biosphere. The biosphere is the sum of all environments on earth that support life. It includes all living organisms in habitats, from bacteria to humans. The biosphere has many layers – from the surface to the core and sea level to space. …
One example of a non-living thing in an ecosystem is rocks. Rocks are not made up of cells and they do not grow in size. Rocks do not depend on the environment for food, water, air or shelter. They do not need energy to survive. All the organisms plus the nonliving components …
In science habitat means a home for an organism that supplies food, water, and shelter. A collection of habitats is known as an ecosystem. The organisms present in an ecosystem are defined as population and communities. The group of organisms living in an area is called a population. Different populations of the …
The living things in an ecosystem are known as biotic factors. Biotic factors include the plant and animal life of a region. Some amazing facts about ecosystems: An ecosystem and its types are determined by geography. Animals and plants within an ecosystem depend on each other for their survival. If conditions change, …
The study of the distribution of animals and plants around the world is known as biogeography. Biogeography is the investigation of geographical distribution of plants, animals and other living things in an ecosystem. Biogeography has further two subdivisions: Phytogeography is the study of plant distribution on the landscape. Zoogeography is the study …
When you look around and observe nature, have you ever wondered how do animals and plants live according to the region and atmosphere? How they are dependent on each other for survival? Scientists have categorized these regions into habitats and ecosystems in which living organisms either live independently or are interdependent. A …
The variety of organisms able to adapt to various environments on earth is called biodiversity. It is the sum of all living organisms in an environment. As biodiversity increases, the whole ecosystem has a greater ability to adapt to changes. There are 3 types of biodiversity: Genetic diversity Species diversity Ecosystem diversity …
