The correct answer is biological.

When any pathogen invades the body, it has to pass several line of defence. The first barrier is skin and mucous membrane which is a physical and chemical barrier. The second line of defence is non specific response by macrophages, neutrophills and interferon. After crossing these two barriers the third line of defence comes into action in which, the B- cells and T-cells acts specifically on the pathogen and destroys it.

Identify two ways in which animals can reduce the intensity of intraspecific competition
MrMuchimi
Intraspecific competition involves an interaction where by members of the same species compete for limited supply of resources. The end result is the reduction in fitness for both individuals. Animals can reduce the intensity of intraspecific competition by exploiting different type of food resources and also moving to other areas that are sparsely populated and with high amounts of food.

the eastern kingbird hunts by catching flying insects in mid-air, an approach which requires impressive and energetic acrobatic
tangare [24]

It is safe to assume that the eastern kingbird will have a <u>type 2 </u><u>functional response </u><u>to an increase in </u><u>prey abundance</u><u>.</u>

The functional response, in ecology, is a data-based description of the behavior of certain animals' consumption rates in response to a change in prey density. This can be of three kinds:

  • Type 1: An increase in consumption
  • Type 2: A decrease in consumption
  • Type 3:  Decreased consumption, followed by a quick increase.

The Eastern kingbird is likely to follow a <u>type 1 </u><u>functional response</u> to the presence of more prey. The reason for this, aside from it being the most common response, is that the eastern kingbird consumes insects, which do not provide a great amount of energy, in a way that consumes much energy. Therefore it is logical to assume that the kingbird will consume more prey to better sustain its rigorous feeding habits.

Predation is when a predator feeds on another organism, which is referred to as the predator's prey.
Alecsey [184]

Answer:

True

Explanation:

Predation is another mechanism in which species interact with each other. Predation is when a predator organism feeds on another living organism or organisms, known as prey. The predator always lowers the prey's fitness. Also, a predator is an organism that eats another organism. The prey is the organism which the predator eats. Some examples of predator and prey are lion and zebra, bear and fish, and fox and rabbit.
