Question

Which of the following ecosystems lacks one or more structured components?
(a) Deep-sea
(b) Freshly formed water pond.
(c) Forest ecosystem
(d) All of the above.

Answer 1

Hint: In any freshly formed ecosystem at first the plants called emergencies start to grow on the edge of the pond, similarly other biotic and abiotic components start growing near the pond over time.

Complete answer:
In a freshly formed water pond ecosystem, many structural components are lacking. Such as the absence of atmospheric conditions and water resources. Structures of an ecosystem mean the organisms and the physical features of the environment that includes the amount and distribution of nutrients in a particular habitat.

Additional Information:
- The structure of an ecosystem also provides information regarding the climate condition of that area. So we can say that structured components include biotic and abiotic components.
- Biotic components of an ecosystem include all the living forms in an ecosystem.
- Based on nutrition, the biotic components can be divided into autotrophs and heterotrophs, and decomposers.
- Autotrophs are also called producers such as plants; they can produce food by the process of photosynthesis.
- Heterotrophs are also called consumers who cannot prepare their food. They depend on other organisms or producers for food.
- Heterotrophs can be further divided into primary consumer, secondary consumer, tertiary consumer, and quaternary consumers.
- Decomposers include saprophytes such as fungi and bacteria. They depend upon dead and decay organic matter.
- They are very much essential for any ecosystem because they help in recycling nutrients to be used by the plants.
- The abiotic component of an ecosystem includes all the non- living forms in an ecosystem.
- It includes water, soil, air, sunlight, minerals, temperature, wind, attitude, nutrients turbidity, etc.
- The deep- sea ecosystem has all the structural components and has greater biodiversity as compared to the freshwater ecosystem.
- The forest ecosystem consists of several types of plants, animals, and microorganisms that live in coordination with its factors of the environment.
- They facilitate the maintenance of the earth’s temperature.
So, the correct answer is '(c) Freshly formed water pond'.

Note:
- The structure of an ecosystem also provides information regarding the climate condition of that area.
- Biotic components of an ecosystem include all the living forms in an ecosystem.
- The abiotic component of an ecosystem includes all the non- living forms in an ecosystem.
- Decomposers are very much essential for any ecosystem because they help in recycling nutrients to be used by the plants.
