As ecological succession began, which of these most likely appeared in the Bastrop forest area first?

Weeds and grasses

If your local environment begins to turn into a desert, what will most likely happen to the organisms in the environment?

A different variety of organisms will be supported rather than the ones that currently exist.

Which event would most likely cause an ecosystem to have the lowest biodiversity and population sizes 3 years later?

A lava flow creates a new section of land

Which observations support the student's claim that the log represents a microhabitat?

A millipedes eating small piece of wood that have broken off the log. A salamander scurried into the shadow of the logs new location . Three types of mushrooms are growing on the log

Which statement below best describes how biodiversity contributes to the sustainability of an ecosystem?

A variety of plant and animal species allows for more survivors of a natural disaster.

Micro habitat

A very small, specialized habitat, such as a clump of grass or a space between rocks

Students in two different schools created gardens at their campus. They only planted native plants that do not require extra care.

Detrivores and decomposers

Which of the following statements best describes the flow of energy in the energy pyramid above?

Each group receives only a small amount of the energy from the level below it.

What is the relationship between ecological succession and equilibrium in an ecosystem?

Energy

During photosynthesis, energy is stored in the chemical bonds of —

Glucose

Which of the following situations contributes to the sustainability of an ecosystem?

Increase in biodiversity

What happens to energy as we move from step to step in a chain or web?

Why is biodiversity important in an ecosystem?

It leads to stability of an ecosystem, which enables it to withstand a disturbance.

In what way is a decomposing log in a forest a microhabitat?

It supports a distinct population of organisms, but the forest houses the log itself.

Four students were asked to observe microhabitats of their schoolyard and describe how microhabitats are able to support different varieties of organisms. Their observations and responses are shown below. Conditions for survival are different in each area

Student 2

Which statement best describes the comparison of lake and ocean environments?

The lake and ocean environments support different organisms because most freshwater organisms cannot live in saltwater.

- consumer eat secondary consumer
