What is carrying capacity?

Back

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

What are biotic factors?

Back

Biotic factors are the living components of an ecosystem, such as plants, animals, and microorganisms, that affect the population dynamics.

What is the difference between abiotic and biotic factors?

Back

Abiotic factors are non-living elements (like water, sunlight, and temperature) that affect ecosystems, while biotic factors are the living organisms that interact within an ecosystem.

How do abiotic factors influence ecosystems?

Back

Abiotic factors such as temperature, water availability, and soil nutrients can determine the types of organisms that can survive in an ecosystem.

What is an example of a density-dependent limiting factor?

Back

An example of a density-dependent limiting factor is competition for resources, which becomes more intense as population density increases.

Front

What is an example of a density-independent limiting factor?

Back

An example of a density-independent limiting factor is a natural disaster, such as a hurricane or wildfire, that affects a population regardless of its density.

Front

How does predation affect population size?

Back

Predation can limit the size of prey populations, as predators reduce the number of individuals that survive and reproduce.

What role do herbivores play in an ecosystem?

Back

Herbivores are primary consumers that feed on plants, and they help control plant populations and serve as food for higher trophic levels.

What is the significance of decomposers in an ecosystem?

Back

Decomposers break down dead organic matter, recycling nutrients back into the soil, which supports plant growth.
