​Ecosystem Interaction

Symbiosis & Trophic Levels​

Interaction between 2 organisms living in close proximity to each other.

• ​Predation

• Mutualism

• Commensalism

• ​Parasitism

​

​Some text here about the topic of discussion.

​Symbiosis

Predator & Prey Relationships

​One hunts and kills the other for food.

​

​Some text here about the topic of discussion.

Predation

​

Relationship where both organisms benefit from each other.​

​

​Some text here about the topic of discussion.

Mutualism

A relationship where only one organism benefits and the other is unharmed.

​

​Some text here about the topic of discussion.

When one organism lives on or in another and one is harmed while the other benefits.

​

​Some text here about the topic of discussion.

​Parasitism

​

Vores

Some text here about the topic of discussion

• Detrivore: ​Eats dead things (decomposer)

​

​Some text here about the topic of discussion.

Focus

​

Lots of Names.....

Producer, Consumer, Secondary Consumer, Tertiary Consumer, Autotroph, Heterotroph

​The Skinny

​Autotroph - Creates it's own energy from the environment around it.

• ​Plants

• Producers

Plants, Producers, and Autotrophs are all interchangeable words.

Some text here about the topic of discussion

​Heterotroph - Eats other organisms to get energy

• Animals

• Consumer (primary, secondary, tertiary)

​Heterotroph, Consumer and Animal are all interchangeable.

​Energy Pyramid

​Energy Transfer

​10% of energy transfers at each level, 90% is lost. Energy begins at the the sun, then to our producers and transfers to our consumers. This is the basic concept that fuels a food web or food chain

Multiple Choice

What is this?

• Food Web

• Trophic Pyramid

• Food Chain

• Trophic Web

Multiple Choice

What is this?

• Food web

• Food chain

• Trophic Chain

• Trophic Pyramid

Multiple Choice

Energy Transfer supports the concepts of the Law of Conservation of Energy which states.

• Energy is created at the sun and then passed on to other organisms

• Energy cannot be created but it can be used up

• Energy cannot be created or destroyed it can only change forms

• Plants create the energy that we all use.

Multiple Choice

Where does the energy go that is not passed in the energy pyramid go?

• It is eaten by lower answers

• It is destroyed

• It is lost the environment as heat or is decomposed as waste

• Nothing is lost ot the environment it is all passed on to the next level.

Multiple Choice

Which describes the components of a Coral Reef Ecosystem?

• The Clown fish and it's eggs.

• The organisms, water, rocks and sunlight in the Coral Reef.

• The sand and water that make up the sea floor.

• The colorful fish, barracuda, fish eggs, and other ocean animals.

Multiple Choice

Lichen is actually 2 organisms: fungi and algae. The fungus has an acid that dissolves minerals in rock providing nutrients for the algae and water for the algae. The algae lives inside the fungus and carries on photosynthesis making food for the fungus.

• A
• B
• C
• D

Multiple Choice

If there is 1000 Kcal available in the producers in trophic level 1, how much energy is available in the herbivores in trophic level 2?

Multiple Choice

Food webs such as the one shown were first used in 1927 by the animal ecologist Charles Elton. The food web below represents the feeding relationships among organisms in an Alaskan ecosystem.

An environmental change that removed which of these organisms from the ecosystem would cause the most instability in the ecosystem?

• Auklets

• Foxes

• Salmon

• Zooplankton

Multiple Choice

Which statement best contrasts food chains and food webs?

• Food webs show a single path of energy in an ecosystem, and food chains show all the overlapping food chains in that ecosystem.

• Food chains show a single path of energy in an ecosystem, and food webs show all the overlapping food chains in that ecosystem.

• Food webs show the path of energy in an ecosystem, and food chains show the path of nutrients in that ecosystem.

• Food chains show the path of energy in an ecosystem, and food webs show the path of nutrients in that ecosystem.

Multiple Choice

Yellowfin tuna are large fish that are found in tropical and subtropical waters around the world. They typically school under objects such as boats or patches of driftwood for protection from predators. Schooling under these structures also provides yellowfin tuna with easy access to a food source, such as smaller herbivorous fish that may be searching for food around the structures.

Which trophic level in an energy pyramid do yellowfin tuna fill?

• producer

• primary consumer

• secondary consumer

• tertiary consumer

Multiple Choice

Which statement about the graph is true?

• When the wolf population begins to increase, the rabbit population begins to decrease

• When the wolf population begins to increase, the rabbit population also begins to increase

• When the rabbit population is at it highest, the wolf population is also at its highest

• When the rabbit population is at it lowest, the wolf population is also at its lowest

Multiple Choice

What is the efficiency of energy transfer between trophic levels of an ecological pyramid or a food chain?

• 90% since majority of the energy is made available to the next trophic level.

• 10% since majority of the energy consumed is used up by the organism.

• 90% since very little is lost as heat.

• 25% since this is the amount that is stored in the cells and tissues of the organism.
