Following the Energy

What is a Trophic Level?

• The position an organism occupies in a food chain, representing a specific feeding level in an ecosystem.

• A measure of the energy efficiency of an ecosystem.

• The total biomass of all organisms in a given area.

• The number of species in a particular habitat.

Herbivores

• Animals that primarily eat meat.

• Animals that are adapted to get their energy and nutrients by eating only plant materials.

• Animals that can eat both plants and meat.

• Animals that do not eat at all.

Carnivores

• Animals that primarily eat plants

• Animals that get their energy and nutrient requirements from a diet consisting mainly or exclusively of animal tissue.

• Animals that can eat both plants and animals

• Animals that primarily consume fruits and nuts

What are Primary Consumers?

• The first level of consumers in a food chain, which are herbivores that feed directly on producers.

• Organisms that produce their own food through photosynthesis.

• Carnivores that feed on other consumers in the food chain.

• Decomposers that break down dead organic matter.

Decomposers

• Organisms that produce energy through photosynthesis.

• Organisms like bacteria and fungi that break down dead organic material, recycling essential nutrients back into the ecosystem.

• Organisms that consume other living organisms for energy.

• Organisms that live in extreme environments and do not require oxygen.

What is a Food Web?

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

• A complex model showing the interconnected food chains and feeding relationships within an entire ecosystem.

• A diagram that represents only the producers in an ecosystem.

• A chart that lists all the animals in a specific habitat.

Scavengers

• Animals that consume carrion, which is the decaying flesh of dead animals that they did not kill themselves.

• Animals that primarily hunt and kill their prey for food.

• Animals that only eat plants and fruits.

• Animals that are known for their speed and agility in catching prey.

What is Biomass?

• The total mass of all living and recently dead organic material within a given area or ecosystem.

• The weight of all inorganic materials in an ecosystem.

• The total number of species in a given area.

• The amount of energy produced by living organisms.

What are producers?

• Organisms that create their own food from inorganic materials, forming the base of every food web.

• Organisms that consume other organisms for energy and nutrients.

• Organisms that decompose organic material and recycle nutrients back into the ecosystem.

• Organisms that rely on external sources for food and energy.

What are omnivores?

• Animals that primarily eat plants.

• Animals that primarily eat other animals.

• Animals that have a diet consisting of a variety of food sources, including both plants and other animals.

• Animals that do not eat at all.
