An insect that has evolved to resemble a plant twig will probably be able to avoid A) parasitism. B) symbiosis. C) predation. D)
bagirrra123 [75]

Answer:

C) predation

Explanation:

Such an insect would serve as a prey to a predator in a prey-predator relationship. Such relationship is a predation.

Predation is an act of feeding in a prey. The preys are weaker and smaller organisms which can easily be overpowered by the bigger predators.

When an insect evolves to resemble a plant twig, it is an evolutionary mimicry. Such organism that evolves must be prey. This presents the prey an evolutionary advantage for it to be evaded by the devouring predator. Mimicry is an evasive tactics.

In parasitism, one organism benefits while the other, the host, suffers from the relationship. Here, the parasite is lives inside the host. A mimicry won't apply here.

Which labels best complete the flow chart?
julsineya [31]

Answer:

The labels that best complete the flow chart are:

X: Free nitrogen is in the atmosphere and Y: Producers captivate components of nitrogen via their roots.

Explanation:

Soil comprises nitrogen, it is taken up by the plants accompanied by other minerals in the process of taking water from the soil. The presence of nitrogen in the soil takes place by the process of decomposition of decaying and dead substances. The process of decomposition dissociates nitrogen and discharges it within the soil. This nitrogen is eventually taken up by the plants.  

Label X shows that in the air presence of nitrogen takes place in its free state, as it is one of the gases found in abundance in the atmosphere of the Earth.
