1: Abiotic VS Biotic Abiotic: Non-living( Ex: Water, sunlight, temperature, precipitation, rocks, and minerals). Biotic: Living (Ex: Plants, animals, bacteria, and microorganisms). |
Predator VS Prey Predators hunt and feed on other organisms (Prey). |
|
|
Parasite VS Host Parasites occupy or feed on another organism (Host). The host organism is always harmed by the parasite. |
Autotroph VS Heterotroph Autotroph: Producers, organisms make their own food (Ex: Plants, cyanobacteria, algae). Heterotroph: Consumers, get nutrients by eating other organisms (Ex: Animals, humans). |
|
|
2: List the 3 types of symbiotic relationships, and give examples of each: Mutualism: Both organisms benefit (Ex: Bees and flowers). Commensalism: One organisms benefits, the other is not affected (Ex: Sharks and remora fish). Parasitism: The parasite is benefiting by harming the host organism (Ex: Ticks and dogs). |
3: Describe the relationship between the following terms: Species, Population, Community, and Ecosystem A species is a group of the same organisms that interbreed; a population is all the individuals in a species in a certain area; a community is all the populations that are present in an area; an ecosystem is all the biotic and abiotic components of a specific environment.

4: How are the movements of energy and nutrients through ecosystems different? Nutrients are constantly recycled in an ecosystem (Cycles). Energy is transferred up the trophic levels and is lost in the form of heat (Energy pyramid). |
5: Differentiate between herbivores, omnivores, and carnivores. Herbivores only eat producers (Plants). Carnivores only eat other animals (Meat-eaters). Omnivores eat both plants and animals. |

6: Describe the 3 models of energy transfer through ecosystems? How is a food chain different than a food web? Food Chain, Food Web, and Energy Pyramid. Food chain shows a single organism at each trophic level. A food web show all the interacting food chains in an ecosystem. |
7: Here is an energy pyramid, starting with 110% of available energy at the first trophic level and the available percentage of energy at each subsequent level. Quaternary Consumers 0.01% 5th Trophic Level Tertiary Consumers 0.1% 4th Trophic Level Secondary Consumers 1% 3rd Trophic Level Primary Consumers 10% 2nd Trophic Level Producers 100% 1st Trophic Level |

8: The similarities and differences between photosynthesis and chemosynthesis. Photosynthesis is used by plants and algae, uses sunlight, water, and carbon dioxide. Chemosynthesis is performed by bacteria in hydrothermal vent communities, uses sulfur compounds, water, and carbon dioxide. Both produce starches/sugars and release oxygen. |
9: How can 2 similar species occupy the same habitat without competing with each other. They live in the same habitat but occupy different niches (Roles) in the habitat. |
