Question

the number of organisms of one species that an environment can support indefinitely is called what?
carrying capacity
population limit
ecological maximum
sustainability index
climax community
growth threshold
what happens when population size exceeds the carrying capacity of the environment?
the population stabilizes
growth continues indefinitely
the amount of resources increase
biodiversity in the area improves
the population declines due to limited resources

Explanation:

• For the first question:
• Carrying capacity is defined as the number of organisms of one species that an environment can support indefinitely.
• Population limit is not the standard term for this concept.
• Ecological maximum refers to the maximum population size that can be supported in a short - term or under certain extreme conditions, not indefinitely.
• Sustainability index is a measure of how sustainable a system (not just a population - environment relationship) is.
• Climax Community is a stable community in ecological succession.
• Growth threshold is not relevant to the long - term support of a population by an environment.
• For the second question:
• When population size exceeds the carrying capacity:
• The population cannot stabilize as there are not enough resources for the excess individuals.
• Growth cannot continue indefinitely because resources are limited.
• The amount of resources does not increase due to over - population (in fact, they may be over - exploited).
• Biodiversity in the area is likely to be negatively affected (not improved) due to resource competition.
• The population declines due to limited resources as there is not enough food, space, etc. for all individuals.

Answer:

• First question: A. Carrying capacity
• Second question: E. The population declines due to limited resources
