Answer:
Dead or diseased trees can serve as a food source for some birds because there are some insects which feed on these dead trees and these insects are eaten by some birds. The body of insects is made of protein so it is a good food for birds. The insects which lived in the dead and diseased trees and feed on it are termites and bugs. Termites are also known as white ants. They feed on dead bodies of plants.
Cyanobacteria were very simple organisms and performed were an role in changing Earth's early atmosphere. They carried out photosynthesis to produce the materials they needed to grow. In this process, they release Oxygen which is needed to sustain life on Earth for Humans and other organisms.
The Prey-Predator relationship is the type of ecological relationship between wolf and moose populations on Isle Royale.
<h3>What do you mean by Ecological relationship?</h3>
The Ecological relationship may be defined as the interaction between the members of one species with respect to the members of the other in response to food, shelter, and space.
Moose are herbivores and the prey of wolfs. It is clearly seen in the graph that when the population of wolves increases, the number of moose decreases. It states that wolfs feed on moose.
Therefore, the Prey-Predator relationship is the type of ecological relationship between wolf and moose populations on Isle Royale.

In two species of birds, both of which form monogamous pair(one male and one female), In species 1, you find that the eggs in a pair's nest are in fact almost always the offspring of that pair. In species 2, you are surprised to find that many of the eggs in a nest were actually fathered by males of neighboring pairs. Apparently, mating outside of monogamous pairings is widespread in species 2. we would expect that female of species 2 would have sperm from multiple males in their reproductive tracts.
- This is because the species 2 are having many eggs.
- These eggs were formed due to fertilization with multiple male bird partners.
- As a result we can expect eggs with different genotypes.
Thus from the above points we can conclude that two species of birds, both of which form monogamous pairs, female of species 2 would have sperm from multiple males in their reproductive tracts
