Unit A #1
Ecosystem
Where Biotic and Abiotic things interact. Can be big (ocean) or small (rotting log).
Types:
Desert
Grassland
Savannah
Freshwater
Tundra
Ocean
Alpine
Garbage Solutions
Recycling (paper, metals, cans, glass)
Composting (grass clippings, food waste)
Incinerating (burning waste)
Sanitary Landfills (prevent leaking)
Quadrats
Triangle, rectangle, circle etc shaped frame for sampling and could find out how many living things are in an area
Species, Population, Community
Species- Individuals that can reproduce
Population- Numbers of the same species that love together
Community- Populations of different species that live and interact in the same area
Consumers, Producers, Scavengers and Decomposers
Consumers- Can't make own food(provides energy for survival), must find/ hunt for it. (Herbivore, Carnivore and Omnivore)
Producers- Make their own food (Plants)
Scavengers- Don't hunt their food, they eat that was already killed.
Decomposers- Decomposers break down dead organisms to return energy back to the soil. (fungi, bacteria)
Needs of living things
Water, Habitat, Energy, Gas Exchange
Cellular Respiration
Every living organism does this (cuz of cells)
It's a chemical reaction that is responsible for the release of energy
Predator & Prey interaction
Prey have Adapted to survive against predators (Camoflauge, speed, enviornment etc)
Food chain and Food web
Food chain- Flow of energy in one direction (Producers, primary consumer, secondary consumer and tertiary consumer.)
Food Web- Flow of energy that is flowed in different direction. If one species is removed, the entire web breaks.
10% of energy is passed on while the other is stored for life support.
Symbiotic Relationships
Commensalism- One species is neutral while the other is benefiting
Mutualism- Both species are benefiting in the relationship
Parasitism- One Species benefits, while the other is harmed
(These relations need at least 2 species)
Water and Carbon cycle
Water cycle: Evaporation -> Condensation-> Precipitation.
Carbon cycle: Carbon is needed by living things, fossil fuels and animals produce it and plants absorb it. Once the plant dies, it is decomposed to the soil or the animals eat the plant w/ carbon
