Explanation:
A food web shows how organisms in a community prey and feed on each other (feeding relationships). It is composed of many interconnected food chains. In addition, it, therefore, shows how energy is transferred up an ecosystem from the primary producers (in this case the trees and grass) to the tertiary consumers (in this case the hawks and wolves).

Answer:
A. Skeletal muscles
Explanation:
An effector is a group of cells, an organ, gland or any part of the body that acts to bring about a change in response to a nerve impulse from the CNS.
In the case of thermogenesis as stated in the question above, where a drop in temperature is detected by thermoreceptors in the CNS, the part of the body that responds in returning the body temperature back to its baseline are the skeletal muscles. The skeletal muscles are the effectors that responded in repeated contracions to generate heat.
Answer:d
Explanation:nematodes are round worms.they live in sea ,land or freshwater habitat.they have an hydrostatic skeleton for movement. They possess a flexible and non-cellular cuticle.They are known for shedding their cuticle. This process is necessary for their growth.an example of nematode is the hookworm.
Arthropods are the most diverse phylum in the animal kingdom.they have jointed appendages and an exoskeleton containing chitin.they may be segmented into head and truck, head, thorax and abdomen or cephalothorax and abdomen.they tend to shed of their exodkeleton during the process of metamorphosis . examples of arthropods include ticks, cockroaches
Correct answer - Heat Energy.
Why? - In every energy transfer, some amount of energy is lost in a form that is unusable. In most cases, this form is heat energy.
Changing environments or major historical events.
