Question
Answer
show Ecology is the study of interactions that take place between organisms and their environment.  
🗑
Adaptation   show
🗑
5 Examples of ABIOTIC factors in an environment (NON-LIVING PARTS OF AN ENVIRONMENT)   show
🗑
show Called limiting factors because they can restrict (limit) the existence, numbers, reproduction of organisms.  
🗑
show The living parts of an environment  
🗑
show -- must be able to successfully reproduce (have babies) -- Offspring (babies) must be fertile (able to reproduce) -- Ex: humans, rattlesnakes  
🗑
Population   show
🗑
Community   show
🗑
show -- all communities interacting with each other AND the abiotic factors -- Ex: pond, field, stream  
🗑
Biome   show
🗑
show an area on Earth where LIFE exists  
🗑
What are the three things needed for an ecosystem to be self-sufficient? (able to keep going and stay balanced)   show
🗑
How are habitat and niche DIFFERENT?   show
🗑
Autotrophs   show
🗑
What is the difference between a photoautotroph and a chemoautotroph? Give examples of each.   show
🗑
Herbivore   show
🗑
show an organism that eats only MEAT  
🗑
Predator   show
🗑
show the animal that is hunted by a predator  
🗑
Scavenger   show
🗑
show an organism that eats BOTH plant and animals  
🗑
Decomposer   show
🗑
Mutualism (+,+)   show
🗑
show A symbiotic relationship between two species of organisms in which ONE benefits and the other is neutral-not harmed or helped  
🗑
Parasitism (+,-)   show
🗑
Producer   show
🗑
Primary/first order consumer   show
🗑
Secondary/second order consumer   show
🗑
Tertiary/third order consumer   show
🗑
show Organisms that break down dead plants /animals and return their nutrients back to the soil Ex: fungi and bacteria  
🗑
show the flow of energy through an ecosystem  
🗑
What is the major difference between food chains and food webs?   show
🗑
Which of the following CAN'T be recycled - Matter or Energy?   show
🗑
What is the % of energy transfer as it passes through a food chain/food web? What is most energy lost as?   show
🗑
What is the carrying capacity of an environment?   show
🗑
What is the difference between a density-dependent factor and a density independent factor that limits population size?   show
🗑
show --Competition (for food/water/shelter/mates)-as population increases, competition increases --Predation (number of predators) --Disease  
🗑
show --Natural Disaster (fire, earthquake, flood) --Harsh climate --man-made: deforestation, pollution  
🗑
show The orderly, natural changes and species replacements that take place in the communities of an ecosystem  
🗑
show Primary Succession : NO SOIL! -Development of new communities in an area w NO LIVING THINGS! EX: After a volcano erupts and kills everything Secondary Succession: SOIL is there -There must be soil present for this to take place
