Question

Which describes a population depending on an abiotic factor?

Answer 1

Answer:

Hello!

I'm assuming the options are:

A) A bean plant does not grow well because it is planted where there are many weedy plants.

B) Coral reef organisms carry out photosynthesis using the sunlight that passes through the clear water above.

C) Squirrels eat eggs from a bird's nest.

D) A hawk preys on a mouse.

The answer is B) Coral reef organisms carry out photosynthesis using the sunlight that passes through the clear water above.

Explanation:

• An abiotic factor is a non-living factor of an ecosystem that influences the biotic factors and the population inhabiting that ecosystem.
• Option A describes competition between two plants. This is an example of a relationship between two biotic factors (bean plant and weeds)
• C again describes the food relationship between two biotic factors (squirrel and bird's eggs).
• D is an example of predator-prey relationship which is also an example of two biotic factors influencing each other.
• B describes how coral reefs (biotic factor) utilizes sunlight (abiotic factor) to produce food and and oxygen through photosynthesis.
