Presentation transcript:

What is the difference between a species and a population?

Species are organisms that are able to interbreed A population is a group of the same species living in a Specific area. Same species but different populations (Connecticut vs. Alaska?)

Q: What things affect a Population? Biotic (Living) Other organisms Predation Food Source Competition Parasites Disease Abiotic (Not living) Weather Air Water (drought, flood) Light Temperature Salinity

Which things are biotic and which are abiotic features of the ecosystem below?

How does the relationship between predator and prey affect the population?

Q: What happens when a species run out of food or space or live? A: Not all the individuals will survive. Each species has a carrying carrying capacity, which is the maximum population size of the species that the environment can sustain indefinitely, given the food, habitat, water, and other necessities available in the environment.

Carrying Capacity Example There is only enough resources on the island to sustain a certain number of deer
