Question

State whether the following statement is true or false:

All food chains begin with a photosynthetic producer.

Answer 1

This statement is false.

Explanation:

While most food chains on Earth begin with photosynthetic producers that use sunlight for energy, an important exception exists in deep-sea ecosystems. In these environments, where sunlight cannot reach, food chains begin with chemosynthetic producers (certain bacteria) that produce food using energy from chemicals, such as hydrogen sulfide, released by hydrothermal vents.
