Answer
ecology   show
🗑
Adaptation   show
🗑
show Examples: 1. Elevation 2. temperatures 3. strong winds 4. type of soil 5. water available  
🗑
Why they ABIOTIC FACTORS often called “limiting factors?"   show
🗑
show The living parts of an environment  
🗑

🗑
Population   show
🗑
Community   show
🗑
show -- all communities interacting with each other AND the abiotic factors -- Ex: pond, field, stream  
🗑
Biome   show
🗑
Biosphere/Ecosphere (LARGEST)   show
🗑
What are the three things needed for an ecosystem to be self-sufficient? (able to keep going and stay balanced)   show
🗑
show Habitat is where an organism lives, But a niche is all strategies and adaptations a species uses in its environment, how it survives & reproduces, etc. A species’ niche includes ALL interactions between the species and its habitat.  
🗑
Autotrophs   show
🗑
What is the difference between a photoautotroph and a chemoautotroph? Give examples of each.   show
🗑
show an organism that eats only PLANTS  
🗑
show an organism that eats only MEAT  
🗑
show an organism that hunts, kills, and eats other organisms  
🗑
show the animal that is hunted by a predator  
🗑
show an organism that eats dead animals  
🗑
show an organism that eats BOTH plant and animals  
🗑
show organisms that break down and recycle dead plants and animals  
🗑
show A symbiotic relationship between two species of organisms in which BOTH benefit  
🗑
show A symbiotic relationship between two species of organisms in which ONE benefits and the other is neutral-not harmed or helped  
🗑
show A symbiotic relationship between two species of organisms in which ONE benefits and ONE is harmed/hurt  
🗑
Producer   show
🗑
show Organisms that eat plants (herbivores)  
🗑
show Organisms that eat other animals (carnivores)  
🗑
show Organisms that eat other carnivores (carnivores)  
🗑

🗑
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
🗑
show -- about 10% of energy is passed from level to level of a food chain -- about 90% is lost as HEAT  
🗑
show the maximum (largest) population size of a biological species that can live in that specific area based on abiotic and biotic resources available.  
🗑
show Density DEPENDENT factor: Depends on the # of population in a given area ( ****Directly connected to the number of organisms in that area!**** Density INDEPENDENT: These factors happen NO MATER WHAT the population size is.  
🗑
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
