Five species of Monotreme exist today. Four species of Echidna. These are egg-laying mammals, and have a cloaca, a single opening that serves for sex, defacation, and egg laying. This is similar to birds, who descended from Dinosaurs.
The fifth species is the Platypus, an egg laying mammal.

Explain why a species that eats only two species of plants may have a higher probability of becoming endangered than a species that eats ten species of plants?
If species A survive only by eating 2 species of plants, then if any of those plants' population decrease, then Species A would have a severe decrease in food. But if Species B survive on 10 plants, even if all of the numbers of those plants decrease, they still have a wider range to find food. So this is why Species B has the better chance of surviving.

Which mammals give eggs?
The platypus and the echidna are both monotremes, that is, egg-laying mammals. There are actually three known species of egg-laying mammals, or monotremes. They are the platypus and short-beaked echidna of Australia, and the long-beaked echidna of Papua New Guinea.

Is there a mammals that no mamary glands?
Monotremes do not have discrete mamary glands, they do still produce milk.
Are monoteres endangered?
There are two main types of monotremes: the platypus and the echidnas. Although humans have caused damage to the habitat of the platypus, they are still considered Least Concern. There are four species of echidnas, also called spiny anteaters. Of the four species, three are critically endangered and the fourth is considered Least Concern.
