Which stage of an insects life cycle is metamorphosis part of?
Growth
Define ecosystem.
Any environment where living things interact with nonliving things.
What is ecology?
The study of biotic and abiotic factors.
How is budding and regeneration similar?
only one parent is needed.
What can be concluded from the following excerpt?
"A MOTH HAS A LIFE SPAN OF ABOUT ONE WEEK. THE OLDEST RECORDED AGE FOR A HUMAN IS 122 YEARS!"
THIS MEANS YOU HAVE ALREADY LIVED LONGER THAN THE AVERAGE MOTH.

2. regeneration
3. fertilization
What can we infer from the following sentence?

EXAMPLE BIRDS BUILD NESTS AND SPIDERS SPIN WEB.
Explain, what is meant by population in an ecosystem.
The number of a certain species within an ecosystem (ex: number of people in a city, a waterlily is a member of the plant population in the pond community.)
Describe how ecosystems and habitats are similar.
They both have living and non living things existing in them.
It is nonliving in the environment.

Explain the stages in complete metamorphosis.
Egg- female lays the egg.
Larva- does not resemble the adult.
Pupa- body changes from here.
Adult- fully grown animal.
Explain budding.
one parent needed, bump grows on the parent hydra,bud growth and development, breaks off and becomes an independant hydra.
Explain the stages in incomplete metamorphosis.
Egg- beginning of life.
Nymph- growth and development.
Adult- reproduction can happen.
Death- can happen at any time.
What is meant by regeneration?
where development of an new organism from part of the parent grows. (ex: new body parts.)
Describe fertilization.
both parents needed to mate, female lays eggs.
