Cycles& Disturbances
Ecological Disturbances, Carbon & Nitrogen Cycles
| Term | Definition |
|---|---|
| Plants in Carbon Cycle | Absorb CO2 from atmosphere during photosynthesis and convert it into glucose, carbon is released back into atmosphere during respiration or passed along when eaten or broken down by decomposers |
| Animals in Carbon Cycle | Consume carbon in plants or other animals, carbon is released during cellular respiration or decomposition |
| Ecosystem | A community of interacting organisms and their physical environment. Contains biotic and abiotic factors. |
| Biotic factors | LIVING things in an ecosystem (plants, animals, bacteria, etc.) |
| Abiotic factors | NONLIVING things in an ecosystem (weather, sunlight, soil, rocks, etc.) |
| Producers | Makes their own food (AUTOTROPHS), Ex- Plants, algae, photosynthetic bacteria |
| Decomposer | Breaks down dead organisms (HETEROTROPHS) Ex- Bacteria, fungi |
| Primary consumer | Eats producers (plants) and is a HERBIVORE or OMNIVORE |
| Secondary consumer | Eats primary consumers and is a CARNIVORE or OMNIVORE |
| Tertiary consumer | Eats secondary consumers and is a CARNIVORE |
| Food web | a community of organisms where there are several interrelated food chains |
| Trophic levels | how organisms are sorted based on their place in the food chain |
| Ecosystem stability | tendency of species populations to remain stable |
| Competition | the struggle between organisms to survive in a habitat with limited resources |
| Carbon cycle | the movement of carbon from the atmosphere into organisms and back again |
| Nitrogen cycle | the transfer of nitrogen from the atmosphere to the soil, to living organisms, and back to the atmosphere |
| Nitrogen-fixing bacteria | bacteria that convert nitrogen in the air into forms that can be used by plants |
| Biomagnification | when toxic substances (like mercury or pesticides) become increasingly concentrated in the tissues of organisms at each higher level of the food chain, reaching harmful levels in top predators |
| Biodiversity | the variety of all living things on Earth—including plants, animals, fungi, and microorganisms—along with the habitats they form and the genetic differences within species |
| Native Species | a species that originated and developed in its surrounding habitat and has adapted to living in that particular environment. |
| Non-native species | a species that originated somewhere other than its current location and has been introduced to the area where it now lives |
| Process that ADDS carbon to the atmosphere | Cellular respiration, decomposition, burning fossil fuels |
| Process that REMOVES carbon from the atmosphere | Photosynthesis, carbon sinks (forest, ocean, soil) |
| Invasive species | a species of plant or animal that outcompetes other species, causing damage to an ecosystem. |
