Answer:</u></h2>
Decomposers and scavengers break down dead plants and animals. They also break down the waste (poop) of other organisms. Decomposers are very important for any ecosystem.
The absence of decomposers in Earth would cause irreversible damage to the planet's wildlife. Carcasses and dead leaves will cover the surface the planet without getting broken down.
If there were no decomposers. Wastes and the remains of dead organisms would pile up and the nutrients within the waste and dead organisms would not be released back into the ecosystem. Producers would not have enough nutrients.
If they weren't in the ecosystem, the plants would not get essential nutrients, and dead matter and waste would pile up and life will end for ever and our beautifull will be destroy.
As the exercise progresses, muscular activity increases venous return. This increases the pre-load on the right ventricle. During venous exercise, the rhythmic pump of the muscles facilitates venous return by forcing the blood through one way valves that lead to the heart. Additionally, increased lung activity which creates a change in thoracic pressure that draws blood towards the heart. Regular exercises improves the venous return by increasing total blood volume, increasing end diastolic volume and increasing the size and contractile strength of the heart muscle.
<span>Answer: Aerobic bacteria cause an infection on the surface of the skin, and anaerobic bacteria cause an infection in a heart muscle.</span>
An aerobic bacteria can survive and grow in a oxygenated environment. A perfect environment is the skin because it's in contact with a lot of oxygen.
On the other hand, an anaerobic bacteria cannot grow in the presence of oxygen. So for them to cause an infection, they need to be in a place without this gas, just like the heart which a deep tissue.
