Ecosystems: Energy Movement through the Ecosystems

Ecosystems: Energy Movement through the Ecosystems

Standard:

L5.3.B Students will demonstrate an understanding of a healthy ecosystem with a stable web of life and the roles of living things within a food chain and/or food web, including producers, primary and secondary consumers and decomposers.

What does this means

Students will take a deep dive into what makes up an ecosystem and how both living and nonliving components interact.

Lesson Objective

Students will describe the components of an Ecosystem!

Quick Question?????

What is Ecology? What is an Ecosystem??

Ecology......

Ecology is the study of the relationships between organisms (living Things) and their environment.

Example: is studying the food chain in a wetlands area

Ecosystems

An ecosystem includes all of the organisms and environmental factors in a certain area. It is simply a unit and can be of any size. As small as your backyard right up to.....the largest ecosystem in the world, the biosphere, which includes every part of the Earth where organisms can survive, such as the earth's crust, its waterway, landforms, forests and the atmosphere. The biosphere is all of the ecosystems on Earth combined. An ecosystem can be broken down into Biotic factors, which are the living and once-living -parts. Abiotic Factors, which are the non-living parts.

Biotic Factors

• Plants

• animals

• fungi

• bacteria

Abiotic Factors

• Air

• Water

• Soil

• Rocks

• Light

Biotic and Abiotic Factors

Biotic and Abiotic factors in an ecosystem interact with each other. They supply the resources that living things need. For example: Plants need air, water, and sunlight to survive. Plans then provide food for many animals that live in that ecosystem.

Abiotic Factors

Air: The atmosphere, the air that surrounds Earth, is an important abiotic factor. Animals Breathe in oxygen and exhale Carbon Dioxide. Plants use Carbon Dioxide for essential processes, like photosynthesis, which uses sunlight, CO2, and water to produces sugar molecules for energy. After using Carbon Dioxide, plants release Oxygen back into the environment. Animals then breathe in oxygen for Respiration, which converts sugar molecules into energy.



Abiotic Factors Cont.

Water: Almost all life processes, such as photosynthesis, respiration, and digestion, involve water. Many plants and animals rely heavily on water not only for sustenance but also for shelter. Water is a habitat for fish and frogs. and many other organisms.

Soil: Soil consists of a mixture of rock and mineral particles, water, and dead organisms. Different soil have different nutrients qualities so different types of plant life.

Sunlight: The root of almost all our food can be traced back to sunlight. Plants and algae capture the sun's energy and use it to produce chemical energy.

Temperature and Climate: Most animals and plants can survive only in a certain temperature range. Temperature is affected by the amount of sunlight a region receives, the angle of that sunlight, elevation, if large bodies of water are nearby, ocean circulation, and other factors. Climate is also affected by the timing and amount of wind and precipitation an ecosystem receives.

Abiotic Factors

Biotic Factors

The biotic factors of an ecosystem include all of its living and once-living parts. Each organism has its own role in the ecosystem. Ecosystems can be small, like a single log or a pond, or very large, like a forest or desert. The place in an ecosystem where an organism lives is its Habitat. Habitats vary depending on the type of ecosystem. The logs in a forest ecosystem provide a habitat for insects, fungi, and moss. Trees and bushes provide a habitat for birds and squirrels. Each living thing has its own niche, a special role that an organism plays in the organism. For example, two birds may share the same habitat in a rainforest canopy but eat different foods. One bird may eat insects while the other eats plants. The birds have different niches in the canopy ecosystem.
