ecology - the study of relationships between living organisms and between organisms and their environment ecosystem - a system made up of organisms as well as the abiotic factors in the area population - a group of organisms of the same species who live in the same area at the same time community - a group of populations living and interacting with each other in an area species - a group of organisms which can interbreed and produce fertile offspring habitat - the environment in w...

What is a "community"? -:- A group of many species organized by interactions What interactions structure the community? -:- Mutualism, Consumption, Competition Who gets harmed, who benefits in each type of interaction? -:- Mutualism- both benefit Consumption- one species benefits, other is harmed Competition- both species harmed, one more than the other How do these interactions create an interdependence underlying community structure? -:- Help structure the community What is a n...

Allopatric populations - closely related species that are geographically separate Aposematic Coloration - warns or danger Batesian Mimicry - Harmless species looks like predator Biotic factors - living portion (animals, plants, decomposers, etc) Bottom-up control - Mineral nutrients, temperature, and light control plants (primary producers)-- Soil nutrient availability can directly enhance vegetative growth, flowering, and fruiting Character Displacement - when natural selection favors tho...

Describe the role of predation in community dynamics and evolutionary outcomes including: Predationavoidance adaptations including camouflage, toxicity+warning coloration, Batesian mimicry, masquerade - Camouflage- Blending into surroundings Toxicity/warning coloration- Warning predators of bad effects if eaten Batesian Mimicry- Mimicking a species with bad effects Masquerade- Look like inedible objects Who gets harmed, who benefits in each type of interaction? - Mutualism- both benefit Co...

what is a biological community? - Answer All of the populations of organisms living and interacting in a particular area commensalism - Answer interaction where one species benefits and the other is unaffected competition - Answer interaction where individuals use the same resources, lowering fitness for both -/- consumption - Answer interaction where one organism eats or absorbs nutrients from the other, +/- mutualism - Answer interaction where two species benefit +/+ three key t...

What is the carbon cycle? Why is it important? - Answer The carbon cycle is the mouvement of carbon between species, the earth, the atmosphere and oceans. Without carbon, ecosystems would not function and persist over time. Most exchanges involve the ocean. What are the crucial processes in the carbon cycle? Why are they important? - Answer Cellular respiration and photosynthesis. They cancel each other out so that there isn't too little CO2 (causing a frozen earth) or too much CO2 (causi...
