Endotherms, such as birds and mammals, use metabolic heat to maintain a stable internal temperature, often one different from the environment. Ectotherms, like lizards and snakes, do not use metabolic heat to maintain their body temperature but take on the temperature of the environment.
A. land plants, tiny water plants
a. slug, frog, newt
b. plants, slug-insect-water fleas, frog-fish-newt, perch-fox, heron
c. water fleas, diving beetles
d. heron, perch

hope this helps!!
