What biotic parts of an environment affect a lizard?

A hawk looking for food; a tree or shrub that may block the sunlight; other predators whom may wish to look for food; and another lizard that may also want that spot of sunlight. (please know that this information is mine and not others, it may help you but to be 100% sure of my answer, please check with your teacher or parent/guardian. I hope this helped you as I know science can be a very tricky subject to master. REMEMBER: You can't memorize science, you must understand it or else the Words mean nothing.)
