Resources in Ecosystem

How do abiotic factors like water and temperature influence the carrying capacity of an ecosystem?

• They have no effect on the carrying capacity

• They only affect the distribution of species, not the carrying capacity

• They determine the types of species that can survive in an ecosystem

• They directly affect the carrying capacity by influencing the availability of resources

Which of the following best describes an ecosystem?

• A collection of different communities

• All the living organisms in a particular area

• The interaction of living organisms with their physical environment

• A group of similar species

What are limiting resources?

• Resources that increase the population size indefinitely

• Resources that have no impact on population size

• Resources that are abundant in an ecosystem

• Resources that restrict the growth of populations

How can the carrying capacity of an ecosystem be altered?

• By introducing new species into the ecosystem

• By removing all the predators from the ecosystem

• By changing the availability of limiting resources

• By increasing the biodiversity of the ecosystem

In an ecosystem, the number of individuals of a species that can be supported by the environment is known as:

• Immigration

• Carrying Capacity

• Limiting Factor

• Adaptation

Which of the following is an example of a limiting factor that can affect the carrying capacity of a population?

• Availability of food and water

• Number of predators in the ecosystem

• Competition between different species

• Variation in climate conditions

What is one way a population can exceed the carrying capacity of its environment?

• By decreasing competition within the population

• By increasing the availability of resources

• By reducing the birth rate

• By overusing the available resources

How does a high population density affect the carrying capacity of an environment?

• It decreases the resources available to each individual

• It increases the birth rate in the population

• It raises the carrying capacity limit

• It prevents competition among individuals

What happens if a population exceeds the carrying capacity of its environment?

• The birth rate decreases

• Competition within the population decreases

• Individuals may die due to lack of resources

• The environment's carrying capacity increases
