Explore the interplay of living (biotic) and nonliving (abiotic) factors within ecosystems, from organisms to communities. Define species, population, and community roles, and illustrate ecosystem components visually. Dive into niches and habitats to grasp the intricate web of interactions.

Ecology:Ecosystems Cornell Notes Page 149
What is Ecology? The study of how living things interact with each other and their environment.
Page 148- divide top 2/3 of page into half vertically. Label one column “Living things” and the other “Nonliving things”
What are Biotic Factors? Living or once living parts of an ecosystem. Plants, animals, insects, bacteria, etc.
What are Abiotic Factors? Nonliving parts of an ecosystem Water, sunlight, air, rocks, temperature, etc.
What is an Organism? An individual, living thing. Use energy, grow, reproduce, respond to environment
What is a Species? A group or “type” of organisms that are physically similar and can reproduce. Ex.) humans
Think and Discuss: How is an Organism different from a Species?
What is a Population? All the members of the same species in an area.
Think and Discuss: How is a Population different from a Species?
What is a Community? All the different populations that live together in an area.
What is an Ecosystem? All the living and nonliving things that interact in an area.
What is a Habitat? The place where a species population lives and provides the things it needs. food, water, shelter
What is a Niche? The role an organism plays in its habitat to survive. Its job. Ex.) Honey bee pollinating flowers
Think and Discuss: What is the difference between a Community and an Ecosystem?
Summary pg. 148 Topic Sentence:Ecosystems are made up of all the living and nonliving things that interact with each other. • Biotic/ Abiotic factors • Organism • Species • Population • Community
Assignment • Fold your paper into 6 equal rectangles. Turn your paper sideways. • Draw a plant or animal in one section. Label it by name and put “organism” under it. • Draw a population of the same organism ( 2 or more) in the next section. Label it population.
Draw a community from the same environment that the organism is found(2 or more species). Just use one section. Label it community. • Use the remaining 3 sections todraw an ecosystem from the same environment that the original organism is found ( include at least 5 living factors, 5 non-living factors). Label them abiotic and biotic items. Label this section Ecosystem. • COLOR ALL sections.
