Answer:

if you are referring to a physical change in a reaction, a physical change is a change that will affect the physical appearance of something without changing the composition (what it is made of)

Explanation:

examples of physical changes are things like changes in texture, change in state (water melting or boiling), change in shape (cutting a piece of paper), change in colour (as long as it is not due to a chemical reaction), change in temperature, etc. All of these changes will not change what the item is made of or what is in it. Some of these changes such as colour, state, temperature can also be caused by a chemical change.

Pyramids depicting the number of organisms or biomass may be inverted, upright, or even diamond-shaped.
Delicious77 [7]

Answer:

The correct answer is - as energy lost at every trophic level.

Explanation:

In any ecological ecosystem the energy pyramids always upright unlike other pyramids such as biomass showing the number of organisms, that can be diamond shape, inverted or upright.

The main reason behind this is due to the fact that it is only a pyramid in the ecosystem that always unidirectional in the food chain which is always some energy lost with an increase in the trophic level in the food chain. This loss of energy always gets back to the atmosphere in each step of the food chain.

How was the knowledge of ecological succession applied to the reclamation of land damaged due to mining?
Mandarinka [93]

After mining, to reclaim the land, the depression is filled with rocks then the top is filled with loosely graded soil. Introduction of early succession plants is important before big trees can grow. The early succession plants help in the breaking down of the rocks into soil hence making the topsoil deeper to support trees.
