A food chain is a diagram used by biologists to better understand ecosystems.
It represents the interrelationships between different plants and animals. The
energy is derived from the sun and converted into stored energy by plants
through photosynthesis, which travels up the food chain. The energy returns
to the ecosystem after the organisms die and decompose back into the Earth.
This process is an endless cycle.
In food chains, living organisms are grouped into categories called primary
producers and consumers, which come in multiple tiers. For example,
secondary consumers feed on primary consumers, while tertiary consumers
feed on secondary consumers. Apex predators are the animals at the top of the
food chain. They are the highest category consumer in an ecosystem, and apex
predators do not have natural predators.

What would a mongoose likely eat according to the food chain diagram?

  • A. Shrub
  • B. Aardvark
  • C. Vulture
  • D. Mouse
Correct Answer: D

Rationale: According to the food chain diagram, mongooses are consumers that feed on smaller animals like mice, making choice D the correct answer. Shrub (choice A) is a plant and not a typical food for mongooses. Aardvark (choice B) is a large mammal that is not a primary food source for mongooses. Vulture (choice C) is a scavenger bird that typically feeds on carrion, not a preferred food for mongooses.
