________: a relationship between two different organisms where both organisms benefit.

Phoresis

________: a commensal relationship where one organism attaches itself to another in order to travel.

Omnivore

________: an animal which feeds on other animals and on producers.

Food Web

________: a way to show all the different feed relationships in an ecosystem.

Commensalism

________: a relationship between two organisms where one organism benefits and the other is neither harmed nor benefited.

Primary Productivity

________: the rate of production of new biomass through photosynthesis or.

Decomposers

________: bacteria and fungi which break down dead organic matter and release the nutrients back into the environment.

Biomass

________: the mass of living material in an area; it can be measured as a dry mass without water or wet mass with water.

Endoparasitic

________: a parasite that lives inside of its host.

Predation

________: a relationship between two organisms where a predator hunts, kills and eats a prey.

Ecosystem

________: the living organisms and the environment with which they interact.

Parasite

________: an organism that obtains nutrients from their host.

Ectoparasitic

________: a parasite that lives on the outside of the host.

Parasitism

________: a relationship between two organisms where the parasite obtains benefit at the expense of the host.

Chlorophyll

________: a pigment found in plants and algae that is used to absorb sunlight for photosynthesis.

Algal Bloom

________: a rapid increase in a population of algae caused when the ecosystem becomes in balance due to excess fertilizers entering the ocean and referred to as a dead zone.

Carnivore

________: an animal which feeds on other animals.

Trophic level

________: the position an organism occupies in the food chain or food web.

Competition

________: a relationship between two organisms where both species are negatively affected as they are trying to use the same resources.

Photosynthesis

________: the process of using light energy to synthesis glucose from carbon dioxide and water to produce chemical energy.

Carbohydrate

________: organic compounds occurring in living tissue that contain carbon, hydrogen, and oxygen (or example, starch, cellulose and sugars such as glucose); ________ can be broken down in the process of respiration to release energy.
