Examples of biotic and abiotic factors are in the top left hand corner.
To the left is a predator-prey graph. It is showing that there is a less population of prey than predators.
How competition for resources might affect the population of a species:
Competition for resources might affect the population of a species because if a species is competing for the same types of resources, soon all the resources are going to be gone and the species will start eating each other, then the population decreases.
Examples of symbiotic relationships:
-Ants and fugi
-Coral and algae
-Bees and orchids
How humans impact the relationship between organisms:
Humans are host to any number of parasites. Humans help different species to evolve and we provide organisms resources to food and energy.

Percent energy loss in an energy pyramid:
As energy passes to a higher trophic level, approximately 90% of the useful energy is lost.
How carbon, nitrogen, and oxygen are cycled through ecosystems:
Carbon- Carbon passes through living things in an ecosystem, soil, and the atmosphere
Oxygen- Through the air and in water.
Nitrogen- Passes through water.

How energy is transferred from one place to another and why energy is never created or destroyed:
Energy can be transferred from place to place by heat waves, light, and sound. Energy can never be created or destroyed because it creates itself and nothing will make it go away.
Examples of renewable and non-renewable sources:
Renewable:
Alcohol
Corn starch
Algae
Solar energy
Non-renewable:
Oil
Coal
Plan to conserve non-renewable resources:
A way that we could save non-renewable resources is using little bits at a time and only when they are needed.
Plan to use more renewable sources:
To use more renewable sources people should start recycling more and having compost piles.
