Synonyms for heterotroph and autotroph Heterotroph- An organism or being Autotroph- An autotrophic organism

Commensalism A type of relationship between two species of a plant, animal, and fungus in which one lives with, on, or in another without damage to either. Parasitism Mutualism A relation between organisms in which one lives as a parasite on another. The relationship between two species of organisms in which both benefit from the association

Food Chain and Energy Pyramid

Differences between a predator/prey relationship and a symbiotic relationship A symbiotic relationship two species living together and includes mutualism, commensalism, and parasitism. In a predator-prey relationship, most often one group must die for the other to benefit.

Coyote competing for biotic and abiotic factors Sunlight- Coyotes live in warm environments and always get sunlight. Water- Coyotes live in dry environments and get little water nearby. Soil Nutrients- Coyotes survive in very dry and poor soil because the roots are able to absorb all the water. Living Space- Coyotes will maintain a territory in a large environment around them. Biotic Factors- Coyotes eat small mammals such as rabbits, mice, voles, and shrews. Coyotes also eat birds, frogs, skunks, berries, insects , beaver, and road-killed deer.

Define a Limiting Factor A Limiting factor is an environmental factor that tends to limit population size.

Water Ecosystem Biotic factors- marine organisms, algae, fungi, and seaweed Abiotic factors- sunlight, water, soil, temperature, and oxygen The difference between a biotic and biotic factors in a ecosystem is that one gets their food from the abiotic factors while the other helps the other one live.

Canadian squirrels’ mating season changing As the spring arrives earlier and lasts longer in northern latitudes, animals that adapt their schedules stand a better chance of seeing their genetic information passed on to later generations, leading to a change within populations.

Effects as pesticides move up the food chain The effect of pesticides is that it kills organisms of a food chain. It starts at the consumer moves up the food chain and eventually kills the top predator making an increase in population of the prey organisms. As a result of biomagnification, organisms at the top of the food chain generally suffer greater harm from a persistent toxin or pollutant than those at lower levels.

how human activities have harmed the ocean Our human activities have harmed the oceans by our pollution and waste thrown into the oceans harming marine animals. 1. Nearby factories travel near oceans and pollute the waters. 2.Trash is dumped from carless people and carried in the wind into the ocean. 3.Oil spills from oil rigs making marine animals suffer the toxic waste.
