Ecosystems and Populations

Front

What is an ecosystem?

Back

An ecosystem is a community of living organisms (biotic factors) interacting with their physical environment (abiotic factors) in a specific area.

Front

Define interdependency in an ecosystem.

Back

Interdependency is the reliance of organisms on each other for survival, where different species depend on one another for food, shelter, and other resources.

Front

What are biotic factors?

Back

Biotic factors are the living components of an ecosystem, such as plants, animals, fungi, and microorganisms.

Front

What are abiotic factors?

Back

Abiotic factors are the non-living components of an ecosystem, including temperature, water, soil, and sunlight.

Front

How do abiotic factors affect ecosystems?

Back

Abiotic factors influence the types of organisms that can survive in an ecosystem and affect resource availability, which in turn impacts population growth.

Front

What is carrying capacity?

Back

Carrying capacity is the maximum number of individuals of a species that an environment can sustainably support.

Front

How does predation limit population growth?

Back

Predation limits population growth by reducing the number of individuals in a population, as predators consume prey.

Front

What is the role of competition in ecosystems?

Back

Competition occurs when organisms vie for the same resources, which can limit population growth and affect species distribution.

Front

How can human activities disrupt ecosystems?

Back

Human activities, such as deforestation, pollution, and urbanization, can disrupt the interdependency of species and lead to ecosystem imbalance.

Front

What is the significance of biodiversity in ecosystems?

Back

Biodiversity enhances ecosystem resilience, stability, and productivity by providing a variety of species that can adapt to changes.
