Studied by 1 personwhat is primary vs secondary succession
primary is the growth of life naturally, secondary is the regrowth of life after a man made disaster (fire)
what are pioneer species
species such as Bacteria, lichen, fungi that first appear during primary succession
what is a climax community
The fully developed, final stage of succession
can two species occupy the same habitat and niche
they can occupy the same habitat, but each species as a unique niche
3 types of symbiosis
Both species benefit - mutualism, One species benefits; one species is harmed - parasitism, One species benefits; one species is unaffected - commenalism
ecosystem organization
Individual - one organism, Population - all members of one species in an area, Community - all living things in an area, Ecosystem - abiotic and biotic things in an area, Biome - ecosystems in the world with similar trends, Biosphere- The entire world and atmosphere
what is the difference between a logarithmic and exponential curve
logarithmic has a limiting factor, exponential does not
what is density dependant/independent
density-dependent are factors that affect a population depending population levels (Competition, Predation, Parasitism, Disease) density independent affect a population corwde dor not (Weather, Natural Disasters, Seasonal Cycles, Human Activities)
What is eutrophication?
When an environment has an overabundance of nutrients (phosphorus and nitrogen) and warm water that result in the expansion of algal blooms
what are the parts of the water cycle
precipitation → evaporation/Transpiration (trees release water vapor) → condensation
how do we get nitrogen into our bodies
by eating plants or animals that consume nitrogen
what turns nitrogen into ammonia, and what is the process called
bacteria, ammonification
What is the name of the process in which some bacteria convert nitrates and nitrites from the soil back into nitrogen gas?
dentrification
