Question

Identify whether each of the following is a biotic or abiotic factor. bear: rock: dead log: grass: sunlight: a mother brown bear and 2 cubs searching for food in the woods. one of the cubs is standing on a wood log.

Answer 1

Biotic factors are living parts of the environment, including dead organic material, while abiotic factors are nonliving elements like sunlight and rocks. A bear and grass are biotic, a rock is abiotic, and a dead wood log can be seen as a biotic element.

Step-by-step explanation:

In Ecology, the environment of an organism includes both abiotic factors and biotic factors. Abiotic factors are nonliving parts of the environment, such as sunlight, rock, and temperature. Biotic factors include all living organisms and what remains after they die, which would include the bear, dead log, and grass.

As for an example given in the question, a mother brown bear and her cubs searching for food in the woods represent biotic factors as they are living organisms, while the wood log would be considered an abiotic factor if it is nonliving.
