Question 1

interspecific competition

Answer 1

the competition between individuals of different species

Question 2

intraspecific

Answer 2

the competition between individuals of the same species

Question 3

What do species compete for?

Answer 3

Species may compete for nutrients (nitrogen, phosphorus, sulfur, iron…), prey, water etc. But species can also compete for the physical space required to live. Typically, the species will compete for the resource that is limiting.
