EcologyThe science of interconnected relationships-Lecture 1Terms:Ecology-

Ecosystem-

Organism-

Species-Levels of Biological Organization

It is important to remember that all parts of an ecosystem are ________________________.Each part is affected by all other parts. If we remove one species from an ecosystem, there could be severe ___________________________________ for that ecosystem.Question:If we remove all the spiders from a given ecosystem:1. Who do you think would benefit?2. What would happen to their population?3. Who would be affected then?

Levels of Organization

Ecologists tend to label ____________________________ of organisms. Lets look at a familiar setting for example: Your house is part of a _________________________; Which is part of a _______________________:which is part of a __________________________which is part of a __________________________.

________ individual organism lives completely on its own. Organisms may live with other individuals of the same species to form a ___________________.Several populations living together make up a ____________________________________.Several communities in a given area make up a ____________________________________.Collectively, all the biomes of the planet earth make up the _________________________________.

Again, the most basic level of ecological organization is the _______________________________.A group of individuals of the same species make up a population.A community is all the populations of living organisms in an area.
