Which of the following is an abiotic factor in an ecosystem?

• Plants

• Temperature

• Rainfall

• Sunlight

What is population dynamics in a community?

• The study of how populations of different species interact with each other.

• The study of how environmental factors affect the growth and survival of a population.

• The study of how the size, structure, and distribution of a population change over time.

• The study of how individuals within a population interact with each other.

How do biotic and abiotic factors interact in an ecosystem?

• Biotic factors have complete control over the distribution and abundance of abiotic factors in an ecosystem

• Biotic and abiotic factors interact in various ways, such as through dependence on abiotic factors for survival and through the influence of abiotic factors on the distribution and abundance of biotic factors.

• Biotic factors have no impact on abiotic factors in an ecosystem

• Abiotic factors are solely responsible for the survival of biotic factors in an ecosystem

What is ecological succession?

• The process by which an ecosystem changes rapidly over time

• The process by which an ecosystem is destroyed over time

What is the impact of human activities on ecosystems?

• Human activities have no impact on ecosystems.

• Human activities can lead to habitat destruction, pollution, climate change, and the loss of biodiversity.

• Human activities only have a positive impact on ecosystems.

• Human activities can lead to the growth and development of ecosystems.
