The answer is (1) decomposer.
(2): Herbivores are animals that consume plants, such as rabbits or deer.
(3): Producers are usually the plants in an ecosystem.
(4): Scavengers are animals that feed off of the remains of other animals already killed by something else (like how a vulture will eat the meat off of dead gazelles after a lion finishes)
(1) decomposer is correct because bacteria and fungi often slowly consume or decompose dead organic material from plants and animals from the ecosystem.
Mitosis occurs in every cell of the body except in germ cells which are produced from meiotic cell division.
Prokaryotic cells do not have a nucleus, animals cells have a nucleus and plant cells have a nucleus. Animal cells and plant cells are both eukaryotic.
