Flashcards do conjunto (20)
- 1What is a Endangered Species?It is close to becoming extinct in all parts of a country or large locations.
- 2What is a Extirpated Species?No longer living in one part of a country but can live in other parts.
- 3What is a threatened Species?When a species is likely to become extinct.
- 4What is a Special Concerned Species?Any species with low or declining number IN A RESTRICTED AREA.
- 5What is a Indicator Species?A species that is sensitive to its environment and warns if the ecosystem is off or not right.
- 6What is a Trophic Level?A trophic level is a category for how an organism gains its energy
- 7What is a Autotroph?A producer, something that can create its own food. Found on the first trophic level.
- 8What is a Heterotroph?A consumer, something that cannot create its own food, so it has to feed on other organisms. Found in other trophic levels.
- 9Name what each Trophic Level is.Trophic level #4- Tertiary Consumer
Trophic level #3- Secondary Consumer
Trophic level #2- Primary Consumer
Trophic level #1- Producer - 10What are Food Chains and Food Webs?Food chains and food webs show the flow of energy from one organism to the next.
- 11How can Temperatures affect the number of organisms?Lower amount of sunlight + Cold temperatures = low producer population
- 12What is Photosynthesis?Solar energy is converted into chemical energy.
- 13What is Cellular Respiration?The process of oxidizing food molecules such as glucose to carbon dioxide and water. Chemical energy of sugar converted to chemical energy.
- 14What is Chemosynthesis?Chemoautotrophs (bacteria) use an alternative energy source to create organic energy molecules.
- 15Rule of 10Only 10% of the energy transferred from one organism to another. Areas of loss: Waste, Thermal Energy, fuel for Cellular Respiration.
- 16Laws of Thermodynamics.1st law: Energy can be transferred from one organism to another, it cannot be created or destroyed.
2nd law: Energy transformations are never 100% efficient, some energy is lost (heat) - 17What is a Pyramid of Numbers?The number of organisms in a food chain that is represented graphically.
- 18What is a Pyramid of Biomass?Shows the total dry mass of organisms at each trophic level of a food chain.
- 19What is a Pyramid of Energy?Shows the total amount of energy transferred through each trophic level.
