Minchanka [31]

Answer: Yes

Explanation:

Carrying capacity can be defined as the total number of members of the population of a species that an ecosystem can sustain in terms of providing resources in the form of food, shelter and others.

<u>Answer:</u> Option C

<u>Explanation:</u>

The rest of the material began to accumulate with the sunrise. The smaller particles moved together to form larger particles that were connected by gravity. As lumps develop, gravity increases and turns into kinetic energy of moving particles that collide and produce heat.
