What Are Ecosystems? Objectives: Main Idea and Details: Compare different climates. Describe how organisms interact in ecosystems. Explain how climate affects ecosystem diversity. Main Idea and Details: Look for details about ecosystems.

Do plants and animals interact in ecosystems? Science Background Do plants and animals interact in ecosystems? How do you think plants and animals interact with each other in nature? Scientists Explain: There are many plant-animal interactions in nature. Animals eat plats to get energy and nutrients. Plants serve as habitats for insects, small animals, and birds. Plans (and algae) also release oxygen into the air as a byproduct of photosynthesis. People and other animals need oxygen to live. Plants use it in the process of respiration.

150 - Ecosystems Science Concepts: -What an ecosystem is and how organisms interact in ecosystems. -What factors affect diversity.

What are the biotic parts (living) of this forest? 150 - Ecosystems 3 What are the biotic parts (living) of this forest? They are the trees, shrubs, flowers, deer, insects, fallen leaves, skunks and birds.

150 - Ecosystems 4 Would the abiotic (nonliving) parts of the ecosystem you see in the illustrations be similar or different from the ones you would see in another ecosystem, such as a desert? The same categories the same (soil, plants, and so on), would be present but the types of rocks, soil, air quality, and so on would be different.

What are the biotic and abiotic parts of an ecosystem? 150 - Ecosystems 5 Main Idea and Details: What are the biotic and abiotic parts of an ecosystem? The biotic parts of an ecosystem are the living parts; the abiotic parts of an ecosystem are the nonliving parts.

150 - Ecosystems Vocabulary: 151 – Ecosystem: an area where organisms interact with one another as well as with the nonliving parts of the environment.

Main Idea and Supporting Details Subheading: Ecosystems Each organism in an ecosystem interacts with other organisms. biotic parts are the living parts of an ecosystem. abiotic parts are the nonliving parts of an ecosystem. an ecosystem’s biotic parts interact with each other. an ecosystems’ abiotic parts help determine what lives in it.

Broad, because it can live in a wider variety of conditions 11 152 – A Place to Live Which has a better chance of survival if conditions change: an organism with a broad niche or one with a narrow niche? Broad, because it can live in a wider variety of conditions

How are a population and a community related in an ecosystem? 12 152 – A Place to Live Main Idea and Details: How are a population and a community related in an ecosystem? A population is a group of organisms of the same species living in an ecosystem. A community is all the populations of an ecosystem.

152 – A Place to Live Vocabulary: 152 – Population: A group of organisms of the same species living together in an ecosystem. 152 – Community: All populations living in an ecosystem. 153 – Habitat: The part of the ecosystem in which the organism lives. 153 – Niche: The organisms role in an ecosystem.

Main Idea and Supporting Details B. Subheading: A Place to Live A population is a group of organisms of the same species living together in an ecosystem All of the populations in an ecosystem make up a community Cacti have connections with many animals of the desert ecosystem Two populations with similar needs can share a habitat Two populations can’t share the same niche.

Removal of one could eliminate others that depend on it for food. 13 154 – Diversity How can the extinction of one species decrease an ecosystem’s diversity over time? Removal of one could eliminate others that depend on it for food.

154 – Diversity Main Idea and Details: Why are climate and location the two most important factors in determining ecosystem diversity? In general, ecosystems closer to the equator are warmer and have more species and so are more diverse. Ecosystems closer to the poles are colder and have fewer species and so are less diverse.

Vocabulary: 154 – Diversity: The variety of species in an ecosystem.

154 – Insta-Lab Marble Diversity: I will pass around a jar of marbles. Reach into the jar, and pull out a handful of marbles. Sort the marbles by type. How many types do you have? Compare your results with those of other tables. Who has the most diverse handful of marbles?

Main Idea and Supporting Details C. Subheading: Diversity Diversity refers to the variety of species in an ecosystem. Climate and location are two of the most important factors. The actions of people are making ecosystems less diverse by destroying habitats and food sources. If one population is harmed or destroyed, the entire ecosystem suffers.

Get your coats because… We are going on a hike!!!! On our hike, with a partner, listen for….look…and list all of the animals and plants you can identify. Extra Credit: On the sheet of paper, illustrate a map of our hike and what you saw/heard along the way.
