Test: Ecosystem - 1 - Class 5 MCQ

As plants are the producers which make food using sunlight, water and nutrients by the process of photosynthesis, similarly animals are the consumers which consume food.

As plants are analogous to flora, similarly animals are analogous to fauna. Herbivores, carnivores and decomposers are all animals that describe a fauna.

There are 6 biomes viz. Arctic Tundra, Deciduous Forest, Desert, Taiga, Tropical Rainforest and Tropical Savanna.

Consumers get their energy by consuming other things such as plants and animals. Plants are the only producers whereas all others are consumers or decomposers.

Carnivores are the part of food chains that are meat eaters.

  Taiga is the largest biome.

Whale lives in ocean.

Living part of an ecosystem is called community.

Question Analysis:
The question asks for the type of organism that is not part of the food chain. The options provided are A) Producer, B) Cons, C) Survivor, and D) Decomposer. We need to identify the option that does not fit into the food chain.

To determine the type of organism that is not part of the food chain, we need to understand the roles of each option in the food chain.
A) Producer:
- Producers are organisms that can produce their own food through photosynthesis or chemosynthesis.
- They include plants, algae, and some bacteria.
- Producers are the foundation of the food chain as they provide energy for all other organisms.
B) Cons:
- It seems that "Cons" is a typo or an incomplete word, as it does not correspond to any known type of organism in the food chain.
- This option can be eliminated as it does not provide any relevant information.
C) Survivor:
- "Survivor" is not a recognized term in the context of the food chain.
- It does not specify the role or characteristics of an organism in the food chain.
- This option can be eliminated as it does not provide any relevant information.
D) Decomposer:
- Decomposers are organisms that break down dead organic matter and recycle nutrients back into the ecosystem.
- They include bacteria, fungi, and some insects.
- Decomposers play a crucial role in the food chain by returning essential nutrients to the environment.
Based on the analysis above, the correct answer is option C) Survivor, as it does not correspond to a recognized type of organism in the food chain.

In a food chain, plants are the producers.
