Today I will study the components of an ecosystem because I need to understand how living things depend on one another.
Essential Question: What would happen to an ecosystem if there were no more bugs? S7L4
What is Ecology? Ecology is the study of how living things interact with one another and with their environment.
What is an ecosystem? All the living and nonliving things that interact in a particular area make up an ecosystem. Examples of ecosystems include: oceans, mountains, and forest
Organism: An organism obtains food, water, shelter, and other things it needs to live, grow and reproduce from its surroundings.
Habitats….. The place where an organism lives and provides its basic needs is its habitat. There can be many habitats in one ecosystem. List at least 3 habitats that you seen outside today.
Biotic Factors: Biotic factors are the living things found inside an ecosystem. List at least 5 biotic factors found in your environment.
Abiotic Factors: Abiotic factors are the nonliving parts of an ecosystem. Examples include: 1.Sunlight 2.Water 3.Oxygen 4.Temperature 5.Soil
Question: How do biotic and abiotic factors differ?
Species: A species is a group of similar organisms that can mate with each other and produce fertile offspring.
Populations: All of the members of a species in a particular area are referred to as a population.
Communities: All the different populations that live together in an area make up a community. Most ecosystems contain more than one type of organism.
What are the levels of organization? Organisms make up populations. Populations make up communities. And communities make up ecosystems.
Our People Can Eat Bread Organism, Population, Community, Ecosystem, Biosphere
Question???? Would all the insects in a forest be considered a population? Why or Why not?
Limiting Factors Anything that restricts or controls the number of individuals in a population
Carrying Capacity The largest number of individuals of one species an ecosystem can support.
Competition All living things compete for – Food – Space Competition limits population growth.
Closing: Minute Paper –What is the most interesting thing you learned today.
