Differentiate between density-dependent and
Setler [38]

Answer/Explanation:

Density-dependent limiting factors are non living and biotic factors that affect the size and growth of a population based on the population density, while density-independent limiting factors are those factors that do not depend on the density of a population before they can have an effect on the growth and size of the population.

Examples of density-dependent limiting factors are predation, disease, Parasitism, competition. These rely on the density of a population in order to affect the growth and size of a population.

On the other hand, examples of density-independent limiting factors are pollution, flood, temperature.

mote1985 [20]

Answer:

Anterior end

Explanation:

You have a pretty good shot at guessing this, because the earthworm has very little going on at the posterior end except the anus. And you probably saw this in lab, too.

I've attached a picture of the earthworm anatomy. Worms can't smell in the strictest sense, but they can use their receptors as kind of a combo smell-taste thing, and those are located in the anterior end.
