What is the gradual growing of a community over time called?

During succession, if a plant needs to grow quickly and make many seeds, would the plant represent a climax species or a pioneer species?

PIONEER SPECIES

Succession occurring in an area composed of bare rock and no soil is an example of ________ _________.

Primary succession

Provide an example of secondary succession. Be sure to include WHY it is secondary succession.

A tornado destroys a field A tornado destroys a field. Small plants begin to grow back in the SOIL remains. Varied Answers.

What is the difference between primary and secondary succession?

Primary succession takes place in an area that has no soil, where secondary succession occurs in when a disturbance occurs at an already established ecosystem where soil exists.

Your friend Thomas is telling you about the nitrogen cycle Your friend Thomas is telling you about the nitrogen cycle. He tells you that nitrogen gets destroyed and we never get it back again. Is he telling you the truth?

No! According to the Law of Conservation of Matter: Matter cannot be created or destroyed!

Matter moves between living and non-living things in ecosystems. TRUE or FALSE Matter moves between living and non-living things in ecosystems.

True! Matter such as water, nitrogen, and carbon all travel from the environment into living things and back again!
