Answer:

Atoms are made up protons and neutrons. An atom is also very small, it is also a unit of matter.

Explanation:

"An atom is the smallest unit of ordinary matter that forms a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms. Atoms are extremely small, typically around 100 picometers across. They are so small that accurately predicting their behavior using classical physics—as if they were billiard balls, for example—is not possible due to quantum effects."

The energy pyramid below illustrates some feeding relationships in alpine meadows of Yellowstone National Park. Which statement

Anettt [7]

Answer:

The answer is - Biomass decreases as energy is transferred from one level to another.

Explanation:

The options are;

A. Chipmunks and insects can occupy the same niche.

B. As the number of bears in this community increases, the number of chipmunks will increase.

C. Insects are classified as omnivores in alpine meadow communities.

D. Biomass decreases as energy is transferred from one level to another

The answer is D. Biomass decreases as energy is transferred from one level to another

The energy pyramid being referred to is in the attachment below.

Biomass is an organic renewable source of energy derived from plants and animals. As animals at the lower trophic levels are consumed by animals at the higher trophic levels there is transfer of energy, however it is not all the energy that are transferred equally. As a result, at each trophic level there is decreased energy and biomass that is transferred from one level to the other.
