Which diagram shows how much energy is used in each trophic level of a system? a. impact system b. food chain c. energy pyramid d. food web

The correct answer is option C, that is, energy pyramid.  

A graphical model of the flow of energy in a community is known as an ecological pyramid. The different levels demonstrate different groups of organisms, which might produce a food chain.  

From the bottom to the top they are mentioned as producers that bring energy from non-living things into the community, then the primary consumers that consume the consumers also known as herbivores then come to the secondary consumers that consume the primary consumers making them the carnivores, and finally the tertiary consumers that consume the secondary consumers.  

The shape of an energy pyramid demonstrates that how the amount of useful energy, which enters every level, that is, chemical energy in the form of food, reduces as it is utilized by the species in that level.  

Thus, the consumers at the top of the pyramid exhibit much less energy in order to support them in comparison to the species that are present near to the bottom of the pyramid. Due to which the numbers of the species at the top of the food pyramid are comparatively less.

Explanation:

idk what the options are but

these is a strong electrostatic attraction between the ions hence a lot of energy is needed to overcome this attraction

this is why the boiling points are so high

answer: grassland biomes are closer to the equator and receive more rain.

grasslands are biomes that are dominated by grasses rather shrubs and trees. savanna are biomes that exhibit grasses, shrubs and small tree as vegetation. grasslands are located near the equator of the earth. these are found in north america. savanna biomes are found in africa, south america, australia and india. grassland exhibit moderate climatic conditions, it receives   amount of rainfall higher than savanna.   therefore, savanna exhibit dry and hot climatic conditions.
