The reproduction that produces genetic variation.
What is sexual reproduction?
Ecosystem is a given environment and also this.
What are all living things in the environment?
This is the process of humans changing a population's traits over time.
What is artificial selection?
A specific path in a food web.
What is a food chain?
A trait this will be expressed when one or two alleles are present.
What is a dominant trait?
The number of parents needed for asexual reproduction to occur.
What is one parent?
Changes in ecosystem are often caused by this.
What is humans?
Natural selection is different from artificial selection in this way.
What is caused by natural changes in the environment?
An organism that creates its own food.
What is a producer?
Asexual reproduction produces this kind of offspring.
What is genetically identical offspring?
This image shows this kind of reproduction.
What is asexual reproduction?
This occurs when a population's resources decrease.
What is a population decrease?
What is selective breeding?
An organism that eats both plants and animals.
What is an omnivore?
The characteristic of an ecosystem with a large variation of organisms.
We use punnett squares to determine this about sexual reproduction.
What is the offspring?
This causes coral bleaching.
What is high temperatures (global warming)?
An earthquake causes a food shortage which makes having a longer neck an advantage is an example of this.
What is natural selection?
These would typically be at the top of a food web.
What is a consumer? (would accept carnivore)
The genotype Bb.
What is heterozygous?
This phenomenon where organisms pass on more desirable traits to their offspring only occurs in sexual reproduction.
What is natural selection?
What is almost always the main reason a population changes?
What is the population's environment?
The person who discovered natural selection.
Who is Charles Darwin?
Food webs show this.
What is the interaction between organisms in an ecosystem?
The best way to get points on a science test.
What is reading the question.
