Question

question 1 1 pts the number of individuals of a species that an ecosystem can support before resource limitations reduce survival is called _________. carrying capacity competition threshold trophic availability realized niche

Explanation:

The carrying capacity is defined as the maximum number of individuals of a species that an ecosystem can sustain indefinitely given the available resources like food, water, and habitat space. Once this number is exceeded, resource limitations lead to a decline in survival rates. The other terms do not match this definition. Competition threshold relates to competition - based population changes, trophic availability is about food - based availability in the food chain, and realized niche is about the actual role and space a species occupies in an ecosystem.

Answer:

A. Carrying capacity
