Natural selection
Who proposed the theory of evolution by natural selection?
Charles Darwin
How is the sun important for the ecosystem?
It is needed for plant growth, habitable climate and the water cycle.
What is the animal on the top of the food chain called?
Apex predator or the tertiary consumer.
The cell cycle is..
the process through which cells grow.
Is the organism that has an advantage more likely to survive or the one without?
The one with the advantage trait is more likely to survive.
How does energy move through an ecosystem?
Energy moves from Producers, Consumers, to then Decomposers.
Where are producers on the food chain?
The very bottom of the food chain, aka the trophic level.
Are animal and plant cells the same?
No they are not.
Inheritance means the advantage of traits..
Will get passed down from parents to offspring.
How does the ecosystem survive in nature?
Through the cycle of energy flow and species independence.
Is the food chain or food web more large and diverse?
The food web is significantly larger.
What phase do cells spend most of their time in?
The interphase.
What IS natural selection?
It Is the process where organisms with traits best suited for their environment are most likely to survive and reproduce
Abiotic vs. Biotic
Biotic are living or once living while
Abiotic are non-living things
What role do decomposers play?
They break down dead plants, animals and waste. (recycling)
How many phases of the cell is there?
Four primary stages.
How can natural selection still act on a trait over multiple generations to favor a specific phenotype?
Reproduction, heritable variation and environmental pressure.
How much energy is transferred from one trophic level to the next?
Only 10%.
Where do you think or know sloths fall on the chain?
Sloths fall in the primary consumer category. (plants and fruits are their main food source)
When does a cell complete its division?
after undergoing mitosis.
