Food Webs + Energy Pyramids

What is a Food Chain?

• A Food Chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another.

• A Food Chain is a circular pattern of energy flow in an ecosystem.

• A Food Chain is a complex network of food webs that includes all organisms in an area.

• A Food Chain is a method of storing energy in the form of food.

What is a Food Web?

• A simple linear sequence of organisms that shows how energy flows.

• A complex network of interconnected food chains that shows how energy and nutrients flow through an ecosystem.

• A diagram that represents the feeding relationships between different species in a habitat.

• A chart that lists all the organisms in a specific area without showing their interactions.

What are Trophic Levels?

• The stages of plant growth in a garden.

• The different levels in a food chain or food web, representing the flow of energy from producers to various levels of consumers.

• The various types of soil found in an ecosystem.

• The different species of animals in a habitat.

What are Producers?

• Organisms that can make their own food through photosynthesis or chemosynthesis, such as plants and algae.

• Organisms that consume other organisms for energy, like animals.

• Organisms that decompose dead matter and recycle nutrients back into the ecosystem.

• Organisms that rely solely on inorganic substances for energy.

What is a Decomposer?

• Organisms that produce energy through photosynthesis.

• Organisms that break down dead organic material, returning nutrients to the soil.

• Organisms that consume living plants and animals.

• Organisms that create new organic material from inorganic substances.

What is an Energy Pyramid?

• A type of renewable energy source

• A graphical representation that shows the distribution of energy among trophic levels in an ecosystem.

• A method for measuring energy consumption in buildings

• A pyramid-shaped structure used for storing energy

What is the role of a Consumer in a Food Web?

• Consumers are organisms that can produce their own food.

• Consumers are organisms that rely on eating other organisms for energy.

• Consumers are organisms that only eat plants.

• Consumers are organisms that decompose dead matter.

What do the arrows in a Food Web represent?

• The flow of nutrients in the soil.

• The flow of energy from one organism to another.

• The direction of water movement in plants.

• The migration patterns of animals.

What are biotic factors in an ecosystem?

• Non-living components of the environment

• Living organisms that interact with other living things in an ecosystem.

• Physical conditions like temperature and humidity

• Chemical substances in the soil and water

What is a heterotroph in an ecosystem?

• An organism that can produce its own food through photosynthesis.

• An organism that must consume food because it can not make its own food.

• An organism that decomposes organic material for energy.

• An organism that relies solely on inorganic substances for nutrition.
