Cycling of matter/Animal relationships
Biogeochemical cycle: the movement of a particular chemical through the biological and geological parts of an ecosystem
Two main processes in oxygen cycling: Respiration and Photosynthesis
Photosynthesis: CO2 +H20 → O2 + Glucose- to create glucose for the plant to use as energy and for continued growth
Chloroplast: in the leaf cells of plants and other producers
Carbon cycle: moves carbon from the atmosphere, through the food web, and back to the atmosphere - building block of life, included in all organic matter, major cause of global warming
Nitrogen cycle: bacteria convert gaseous nitrogen into ammonia, nitrogen moves through the food web and returns to the soil during decomposition, used in proteins and enzymes for plant growth
Natural disruptions: volcanic eruptions, forest fires, landslides, earthquakes, living organisms
Human disruptions: poor farming practices, burning fossil fuels, deforestation
Global warming/climate change: burning fossil fuels adds too much CO2 into the atmosphere that happens faster than treess can reabsorb it, greenhouse gasses absorb heat energy and trap it in the atmosphere causing the planet to heat up
Predation: predator/prey, one organism captures and eats the other - fight/flight
Competition: organisms of same or different species that are trying to use the same resources - territorial displays
Intraspecific: between members of the same population
Interspecific: between different species with a niche overlap
Symbiosis: a close relationship between 2 species where it benefits
Mutualism: a relationship between 2 organisms in which both benefit
Commensalism: a relationship between 2 organisms in which one is helped and the other is neutral
Parasitism: one organism feeds off the other, the host is harmed and can be killed
