both benefit (bee and a flower) 81. Define these types of relationships (symbiosis). a. mutualism – b. commensalism – c. parasitism – d. predator/prey – e. competition – both benefit (bee and a flower) One benefits, the other is unaffected (bird’s nest in a tree) One benefits, the other is harmed (tick and a dog) Predator hunts prey Two organisms fighting for similar resources

82. What is carrying capacity? The maximum amount of individuals in a population that the surrounding environment can sustain

NITROGEN CYCLE 102. How might humans impact the nitrogen cycle? Over fertilization of crops Burning of fossil fuels Deforestation Population growth 105. Plants rely on nitrogen for survival

Carbon cycle How might humans impact the carbon cycle? Burning of fossil fuels Deforestation What are carbon reservoirs? Plants Fossil fuels Oceans atmosphere

Ecological succession 106. This picture is showing primary succession because it begins with bare rock. Secondary succession has soil layer already in place.

Ecological succession Pioneer species are the first species to inhabit an area Ex: Lichens, Moss, bacteria

Ecological Succession The climax community is the final community in which all the populations are stable and unchanging This stage will have the most diverse of species
