Continuation Flashcards
Biotic factors?
Living organisms that affect an ecosystem
Abiotic factors?
Non living organisms that affect the ecosystem
What are the producers?
(Also called autotrophs) they make their own energy mainly through:
- Photosynthesis
- Chemosynthesis
Consumers
Organisms that rely on organisms for energy (food)
Heterotrophs
Symbiosis
When two or more organisms live together in order to survive. Ex. Is commensalism, mutualism, neutralism and parasitism.
Parasitism
Interaction when one species directly harms the other and the other serves as its host (gives itself)
Neutralism
Two species interact but none of them affect each other
Mutualism
An interaction with 2 species that benefits both
Commensalism
When two species live together, one benefits and the other does not lose nor win anything
Food chain
Cycle where organisms transfer energy by eating and being eaten
What order does the food chain go
- Producer (with sunlight and water)
- Primary consumer
- Secondary consumer
- Tertiary consumer
- Apex predator
- Decomposer
Rules of energy pyramid
- the lower the level, the more energy, for example: producers = 100%, apex predators = 0.1%
- the energy is lost as heat
- all animals decompose and recycle in order to be used again
Biomass Pyramid
- represents the living organic matter at each tropic level
- the higher and stronger the level, the less biomass
- for example, apex predator = 9 kilocalories per square meter, primary producers = 9000 kilocalories per square meter
Biome
A regional area that is characterized by the plants, animals and climate there
The different adaptations are:
- Behavioral
- Physiological
- Structural
