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.
Both organisms are composed of cells, the basic unit of life, with each cell surrounded by a cell membrane. The biggest difference between prokaryotes and eukaryotes is that eukaryotes have a nucleus. They also have other membrane structures called organelles.
<u>Answer</u>: can be almost any size
<u>Explanation</u>: Plants are extraordinary organisms that come in a variety of shapes and sizes. The smallest is the watermeal (<em>Wolffia globosa</em>). With sizes of approximately 2 millimeters (0.079 in), it is also the smallest flowering plant in the world. One of the largest are the sequoia with heights of 70-85 meters and ages of over 3000 years old.
Plants are usually divided into two groups depending if they produce seeds or not. Thus, the three group title is unsuitable. As shown above, plants can reach extremely large sizes so the second title is unsuitable too.
All multicellular organisms contain specialized tissues, not only plants. Plants use active transport too and do not rely solely on diffusion. The last tile is also unsuitable as some plants do have true stems and leaves.
