An ecosystem is simply a collection of communities of plants, animals, and microbes interacting together and with their physical environments.
<h3>Energy flow in an ecosystem</h3>
Energy enters the ecosystem through a group of living organisms known as the producers. the producers are mainly the green plants that are capable of photosynthesizing.
Photosynthesis converts solar radiation from the sun to chemical energy in green plants. Another group of organisms in the ecosystem, the primary consumers, feed directly on the producers and as such, are able to gain some energy from them.
The secondary consumers obtain their own energy by feeding on primary consumers. Tertiary consumers feed on the secondary consumers for their own energy and the food chain goes on and on.
Only about 10% of the available energy in one trophic level goes to the next trophic level. The rest of the energy is lost as heat to the surroundings. Thus, the producers have the highest energy in the ecosystem while organisms at the top of the food chain have the lowest energy.

They are all made of carbon
Explanation:
Diamond, graphite, and fullerenes are all made of carbon.
Hope this helps!
Answer:
Car B has more inertia than Car A
Explanation:
Given that,
Mass of car A = 1500 kg
Mass of car B = 2000 kg
Inertia is directly proportional to the mass of an object. Inertia is the measure of the mass of an object.
In this case, the mass of car B is more than that of car A, it means the inertia of car B is more than that of car A.
Hence, the correct option is (c) "Car B has more inertia than Car A".
Answer:
Explanation:
Hello,
In this case, the undergoing chemical reaction is:
Thus, since the diphosphorus pentoxide to water molar ratio is 1:3 and we are given the mass of both of them, for the calculation of the maximum mass phosphoric acid that is yielded, one could first identify the limiting reactant, for which we compute the available moles of diphosphorus pentoxide (molar mass 142 g/mol):
And the moles of diphosphorus pentoxide that are consumed by 13.5 g of water (molar mass 18 g/mol):
Hence, since less moles of diphosphorus pentoxide are available, we sum up it is the limiting reactant, therefore, the maximum mass of phosphoric acid (molar mass 98 g/mol) is computed by considering the 1:2 molar ratio between them as follows:
Regards.
When two object occupy the same space or have the same volume, but one of them is heavier than the other. This means that the heavier object is having a higher mass which results in a higher density than the other (lighter) object.
Note that density is calculated using the following rule:
density = mass / volume
