Answer: Microorganism activity affects soil acidity and the amount of organic matter in soil. It also affects the nutrient and mineral levels in soil as well as soil structure.
Explanation:
The food chain in a visual representation of how energy is flowed through out a specific environment. While it is very similar to the food web, the main difference is that the web gives a more broad wide range of organisms and it is more specific with what eats what. The second part of your question about a few animals roles umm... Grass is a producer which has the role of feeding primary consumers, it is the base of the chain or web without it the whole thing would collapse. Tertiary consumers such as owls have the role of eating secondary consumers. I always thought of it like the tertiary consumers are population control since nothing eats them they have no responsibility to feed other organisms just make sure that secondary consumers don't overpopulate.
Answer:
1). Renewable energy resources include: solar, wind, water (hydro), biomass, and
2). Nonrenewable energy resources include: coal, nuclear, oil, and natural gas.
Explanation:
Renewable energy resources are replenished naturally and over relatively short periods of time while Nonrenewable energy resources as their name applies are limited in their quantity and supplies too.
These forms of energy are primary formed when fossil fuels are destroyed by use, i.e they are not been recovered(nonrenewables); which brings in alternative sources(renewables).
Human supplies of fossil fuels and minerals are dwindled fast. These are nonrenewable resources as we cannot produce them by any process. Our demand for these limited resources, however, is constantly increasing. So we to cut down their wastages, find acceptable alternatives and also recycle them where possible.
Answer:
<h2>Digestion in sponges is intracellular.
</h2><h2>Cnidarians carry out extracellular digestion
.</h2>
Explanation:
digestive process in cnidarians differ from sponges
1. i) sponges have intracellular digestive system.
ii). They feed on planktons by filtering water.
iii). Digestion takes place completely in choanocyte cells.
Cnidarians
1. i) Cnidarians are predators and feed on small fish, krill and many small species.
ii )All cnidarians are carnivores and have very simple body structures adapted as predators.
iii) Cnidarians carry out extracellular digestion. Enzymes break out the food into small particles. Cnidarians have an incomplete digestive system and have only one opening.
