B.)droughts and floods
C.)predation and disease
D.)biotic and abiotic factos​

Answer 1

Answer: D.)Biotic and Abiotic factors

Explanation: The living things in an ecosystem are called biotic factors. Living things include plants, animals, bacteria, fungi and more. The non living parts of an ecosystem are called abiotic factors. In an ecosystem some abiotic factors are sunlight, temperature atmospheric gases water and soil. These would not limit pop growth as much as predation and disease.
