What effect does resource availability have on carrying
capacity?
A. Resource availability sets reproductive rate.
B. Resource availability sets the limit.
C. Resource availability sets primary consumer
productivity

B. Resource availability sets the limit.

Explanation:

The more resources available, the higher the carrying capacity, the less resources available, the lower the carrying capacity.

For example, take a grassland. Let's say that the grassland can support 100 deers. if there was a sudden drought, causing most of the grass to die, the carrying capacity can drop down to 10. If there was suddenly constant adequate rainfall, and silt was deposited in the land, causing more grass to grow, the carrying capacity can grow to upwards of 125.

these macromolecules could either be amino acids, proteins or nucleic acids. they are responsible for the chemical changes and reactions that affects largely the cell and its composition. take for instance the cytoplasm of the cell where these organelles are settled. these simple organelles are composed of macromolecules which ignites and catalyses different functions that enables cells, in macro-perspective in motion and metabolism. in intestines for example, metabolism happens and breaking down parts of a food to simpler compounds that are used and these nutrients delivered throughout the body and again broken down by into smaller components.
