Biology
1 answer:
choli [55]3 years ago
8 0
In general, echinoderms typically respire by simple diffusion, using gills or specialized projections, like tube feet or pockets, to circulate water and oxygen through their bodies. Many echinoderms also use a simple hemal system, a series of pockets and tubes that serves almost like a net of veins and arteries.

posledela

Answer:

The correct answer would be b.  Their numbers will soon decrease.

Bobcats are opportunistic carnivores that feed on various types of prey such as mice, rabbits, voles, mountain beaver, gophers, yellow-bellied marmots, insects, birds, reptiles, and carrion.

If a group of Bobcats moves at the bottom of the mountain, then they will start hunting and eating all the prey available in the area.

C)
dybincka [34]

Answer:

Plants and trees are the primary sources of food for a food chain or a food web. If the population of the primary producers reduces than it affects the whole food web. If the deciduous trees are destroyed due to a fire, there will be less food available for the primary predators. As a result, competition will begin between them and their population will decline. Due to this, the population of other organisms which fed on the primary consumers will also decline.
