Question

Which of the following is not a terrestrial ecosystem?
Forest, Grassland, Aquarium, Desert

Answer 1

Hint:An ecosystem is a geographical area where plants, animals, bacteria and other organisms live together and perform various functions. Ecosystem describes the relation between the biotic (living) and abiotic (non living) components.

Complete answer:
Forest ecosystem:
>Forest ecosystem is a terrestrial ecosystem.
>A forest ecosystem consists of soil, trees, insects, animals, birds and man that interact with each other and also with the environment.
>A forest is a large ecosystem so it has greater species diversity.
>Forest ecosystems also consist of abiotic components such as water, soil, air.
>Biotic components include producers, composers and decomposers.
Grassland ecosystem:
>Grassland ecosystem is a terrestrial ecosystem.
> Grassland ecosystems are the areas where grasses dominate.
>Grasslands occur naturally in all the continents except one continent i.e. Antarctica. Grasslands are the largest biomes on Earth and dominate the landscape worldwide.
>There are different types of grasslands such as natural grasslands, semi-natural grasslands and agricultural grasslands.
>The grasslands are dominated by the herbaceous and shrub vegetation.
Aquarium ecosystem:
>Aquarium is the marine ecosystem.
>Aquarium is defined as a closed artificial marine ecosystem.
>Aquarium ecosystem consists of fishes and plants interacting with each other and with their environment.
>Each aquarium must be consciously designed, developed and managed to facilitate all the functions happening in that ecosystem.
Desert ecosystem:
>Desert ecosystem is a terrestrial ecosystem.
>Desert ecosystem is the study of interactions between the biotic and abiotic components of the desert area.
>Deserts are the arid regions with warm temperatures.
>Cold temperature can also exist in deserts.
Deserts can be found in every continent. Largest desert located in Antarctica, the Arctic, Northern Africa and Middle East.
Therefore, it has been clear from the above discussion that Aquarium is not the terrestrial ecosystem. Forest, grassland, desert all are the terrestrial ecosystem.

Note:Ecosystems are too necessary for all the living beings existing on this Earth. We as humans totally depend on a healthy ecosystem in order to survive or remain healthy. For example – we need pure air in order to breathe, clean water to drink, healthy food to eat that we obtain from the plants, etc.
