Ecosystems and the Nutrient Cycle
The forest is an ecosystem (community of living organisms interacting with non-living components)

Habitat
Habitat
An environment where something lives Ecosystem – a living community that depends on each member and its surrounding environment (cooperating together to survive)

Living things in the forest (biotic) –
Living things in the forest (biotic) –
Producers – living things that use energy from the sun to produce their food.
Consumers - living things that eat the producers
Three types of consumers – herbivores, carnivores and omnivores
Decomposers – living things which feed off dead plants and animals
They reduce the remains to nutrients and minerals for the soil
Examples – mushrooms (fungi) and bacteria
Non-living things (abiotic) in the forest –
Non-living things (abiotic) in the forest –
water, rocks, sunlight, air, soil and chemicals.

The Water Cycle
The Water Cycle
We have reviewed the water cycle from last year to understand the contribution of water in ecosystems.

Photosynthesis
Photosynthesis
Photosynthesis is the process in which green plants use sunlight to make their own food. Photosynthesis is necessary for life on Earth. Without it there would be no green plants, and without green plants there would be no animals.
Photosynthesis requires sunlight, chlorophyll, water, and carbon dioxide gas. Chlorophyll is a substance in all green plants, especially in the leaves. Plants take in water from the soil and carbon dioxide from the air.
Photosynthesis starts when chlorophyll absorbs energy from sunlight. Green plants use this light energy to change water and carbon dioxide into oxygen and nutrients called sugars. The plants use some of the sugars and store the rest. The oxygen is released into the air.
Photosynthesis is very important because almost all living things depend on plants for food. Photosynthesis is also important because of the oxygen it produces. Humans and other animals need to breathe in oxygen to survive.
Some living things other than plants also make their own food through photosynthesis. They include certain types of bacteria and algae.

Forest Ecosystem Jigsaw Project.docxEcosystem Bulletin Board Project
Ecosystem Bulletin Board Project
Students will be tasked with collaborating with a group to create a class bulletin board of a forest ecosystem. Each group will be responsible for representing a different section of the ecosystem and create visuals and notes for their section. Together we will put all sections together to create one comprehensive display that shows:
Photosynthesis
Water cycle
Nutrient cyle
Layers of the forest
Food chains/webs
Biotic and abiotic factors
Importance/values of trees and forests
Trees and Forest- Quiz Part 1.pdfEcosystem Quiz
Ecosystem Quiz
Students will use the notes provided, bulletin board project and Kahoot Review to study for a quiz on ecosystems. The concepts that will be looked at are:
Photosynthesis
Water cycle
Nutrient cycle
Layers of the forest
Food chains/webs
Biotic and abiotic factors
Importance/values of trees and forests
