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.
Explanation:
Plants also have adapted to the Arctic tundra by developing the ability to grow under a layer of snow, to carry out photosynthesis in extremely cold temperatures, and for flowering plants, to produce flowers quickly once summer begins. A small leaf structure is another physical adaptation that helps plants survive. Plants lose water through their leaf surface. By producing small leaves the plant is more able to retain the moisture it has stored.
Answer:
It is necessary.
Explanation:
If a member of a species doesn't reproduce, other members of the same species will become extinct.
A medium. Like water or air or a brick wall.
Answer: The external submucosa I'd the layer of the alimentary canal that contain the blood vessels,glands and nerve plexus that help to regulate digestive activity.
Explanation:
The alimentary canal or gastrointestinal tracts is the organ in the body that helps to break down ingested food into pieces that can be absorbed by human body and expels unwanted food as wastes. The alimentary canal consists of structures from mouth to the anus. The alimentary canal have four distints layers which are the the mucosa, submucosa,muscular layer and serosa.
The mucosa is the inner layer of alimentary canal and it surrounds the lumen. This layer have direct contact with digested food.
The submucosa consists of dense connective tissues, blood vessers, glands and nerve plexus. It regulate digestive activity.
The muscular layer consists of inner circular layer and longitudinal circular layer. It prevents food from going backward.
The serosa is the external layer of the alimentary canal and iits have several connective tissues.
