Population Flashcards
What will populations grow until?
Populations will grow until they become stressed, (share resources, food, water, shelter, competition)
What is carrying capacity
Caring capacity is known as equilibrium (#of births - deaths)
What are limiting factors?
Are environmental factors that prevent an increase in the number of organisms in a population or prevents them from moving into new habitat
What are abiotic limiting factors
Sunlight, water, soil, air, natural disasters such as fires, storms and droughts and human disturbances such as logging and pollution
What are biotic limiting factors?
Competition for resources, predators, reliance on other organisms for survival mutualism, disease, and Parasitism
Define steady state
Most species population will naturally go up and down through out the years because there are natural limiting factors keeping their numbers in check
What species have exponential growth?
The human population is the only species other than bacteria or viruses that will grow beyond the carrying capacity which is called exponential growth
