This is the name given to consumers on the third trophic level of the pyramid
What is Secondary Consumers
100
Elements or pure substances make these
What are nutrients
100
The Earth's surface including 100km down into the Earth
What is the lithosphere?
100
What are the three main types of symbiosis?
Mutualism, commensalism and parasitism.
100
What is the formula for cellular respiration?
Oxygen + Glucose = Carbon Dioxide + Water + Energy
200
This is the source of a scavengers food
What are dead animal remains
200
Moving nutrients back and forth between biotic and abiotic parts of an ecosystem
What is a nutrient cycle
200
What is the difference between a marine biome, and a freshwater biome?
Marine biomes are in the ocean's salt water, and freshwater biomes are in freshwater.
200
What is competition?
The interaction between two or more organisms competing for the same resource in a given habitat.

Name three reasons why plants are important to ecosystems and Earth.
They create oxygen for us to breathe with. They allow energy to be passed into the ecosystem. We get our cellular respiration by eating organisms that got their oxygen from plants or plants directly. There are other possible answers.
300
This is the breakdown of how energy is distributed once acquired by an organism
What is 60% waste, 30% cellular functions and 10% body tissues
300
When plants release water vapor into the atmosphere
What is transpiration
300
Fish swim in which component of the biosphere?
The hydrosphere
300
What is the difference between predation and parasitism?
The predator kills its prey however a parasite feeds off its host while it is alive and lives on or in the host.
300
What two types of plants create the most oxygen in the world?
Algae and trees.

These are two ways to describe grass as seen on a trophic pyramid
What are Producers and Autotrophs
400
Where matter accumulates
What is a reservoir

How many terrestrial biomes are there in Canada? Name one.
Five. Deciduous forests, Boreal Forests, Tundra, Grasslands, Temperate Coniferous Forests.
400
The relationship between a bee and a flower.
What is mutualism?

Photosynthesis is a process plants use to obtain energy from glucose. That is why it is important in a sustainable ecosystem. Explain whether you agree or disagree and why.
Disagree. Photosynthesis is a process plants use to create the glucose while cellular respiration is used to actually obtain the energy.
500
This is the difference between the consumption of energy by a decomposer and a detritivore
What is direct and indirect consumption of organic waste
500
Converts nitrates back into nitrogen gas
What is denitrifying bacteria
500
How are terrestrial biomes classified?
By climate and plant life
500
What is the interaction: Mistletoe lives on and feeds off of a tree. The tree is harmed, but not immediately.
Parasitism

If all plants lost their chlorophyll, why might this be an issue to the ecosystems and the Earth?
Chlorophyll allows the plants to take in the energy from the sunlight, so without it, plants wouldn’t be able to complete the photosynthesis process which would stop the energy flow and cellular respiration in the ecosystems/Earth.
