Why should organisms that produce more offspring have a more likely chance of survival?

Organisms must struggle to get what they need to survive, competing against other organisms that want the same things they do.

Explanation:

I will try to put this in the simplest terms I can:

If you think about it, organisms actually do not live that long. There are multiple cause and effect reasons, such as low resources, no food, extinction, and so on. Thus, organisms must produce offspring to keep their "family line" consistent.

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands

a. suckling by young

b. hypothalamus

c. dopamine

d. trh

e. anterior pituitary

f. mammary glands

g. milk production
