An ecosystem includes all of the living and nonliving factors in a given area. that is, it includes all of the organisms (e. g., plants, animals) that live in an area and the environmental factors (e. g., water, soil, climate) that affect the organisms. what is one criteria that must be met in order for an ecosystem to be stable? a. the amount of available resources in the ecosystem must change at a predictable rate. b. the population size of every organism living in the ecosystem must increase over time. c. there must be less energy flowing into the ecosystem than flows out of the ecosystem. d. the different species of organisms within the ecosystem cannot interact with one another.

A. The amount of available resources in the ecosystem must change at a predictable rate.

Explanation:

This is one of the requirements that would allow an ecosystem to be stable. In order for an ecosystem to remain stable, the amount of available resources in the ecosystem must change at a preditable rate. If this is the case, then the organisms living in it will know what they should expect and they will be able to adapt. If the resources suddenly increase, populations will explode, threatening the balance among species. If the resources unexpectedly decrease, then populations could be wiped out.

what do the different brain waves do?

explanation:

brainwaves are produced by synchronised electrical pulses from masses of neurons communicating with each other. brainwaves are detected using sensors placed on the scalp. brainwave speed is measured in hertz (cycles per second) and they are divided into bands delineating slow, moderate, and fast waves.
