Eco Org & Biomes
The third level of ecological organization that includes organisms from all the different species in an area
What is community?
In the following food chain, the butterfly is this trophic level.
Flower's nectar --> Butterfly --> Frog --> Heron
What is primary consumer?
Jeo-PARTY: Everyone answers
Draw a food web including at least one of each: a producer, an herbivore, an omnivore, and a carnivore
On your board, any mistaken arrows loses the points
A physical or behavioral trait that helps an organism survive in its environment is called this.
What is an adaptation?
The definition of an invasive species.
What is a species from a different ecosystem that causes environmental or economical harm.
This biome is known for lots of trees that change with the seasons. There are usually 4 distinct seasons in this biome.
What is the Deciduous Forest (Temperate)?
Another name for the highest trophic level that describes a species with few other organisms that eat it.
What is an Apex Predator?
This organism eats dead plants and animals and helps recycle nutrients into the soil.
What is a decomposer?
Tapeworms feed on mammals and benefit while the host is harmed. This type of symbiotic relationship is an example of this.
What is parasitism?
The term for the wide variety of all life on Earth. Introducing invasive species reduces this harming the ecosystem.
Biodiversity
This biome is known for having lots of grasses and seasonal droughts, often home to buffalo and prairie dogs.
What are the Grasslands?
The amount of energy passed from one trophic level to the next by percentage.
What is 10%?
This is the term for chain reaction that happens in a food web when one species is added or removed like the wolves in Yellowstone National Park.
What is a trophic cascade?
Clownfish live among sea anemone tentacles and are protected from predators while the anemone is not harmed. This type of relationship is called this.
What is commensalism?
A way invasive species often spread.
Human interaction, accidental or purposeful, sometimes through storms and ocean currents
This biome is a cold biome with little precipitation. Its known for having many coniferous trees in its snowy forests.
What is the Taiga (Boreal Forest)?
In the following food chain, this organism is likely has the highest population in the ecosystem.
Aspen Tree --> Deer --> Wolves
What are Aspen trees?
What happens first in the food web on the board if Hawks disappear from the ecosystem?
Mice population increase
Rabbit population increase
Snake population increase
An organism disguises itself as another more dangerous organism to avoid predators. An example is some fly species have yellow stripes to trick attackers into thinking they are bees instead.
What is mimicry?
The blanks should be filled with these three terms.
1. Organism
2. ___________
3. Community
4. _____________
5. Biome
6. _______________
What are 2. Population, 4. Ecosystem, and 6. Biosphere?
Why do most food chains not go past 4 or 5 trophic levels? (Go past tertiary consumers)
There isn't enough energy to support the higher levels.
What would happen in the food web on the board if an invasive species was added that ate too much grass? (name 3 effects)
The grass would die out, herbivores would starve first, then secondary consumers.

Describe as many adaptations as you can of any organisms you've learned about this year! (Remember the FULL definition of adaptation.)
If you got 5 good examples, you get 500 points
The yucca plant and the yucca moth have a special mutualist relationship. What would happen to the moth if a new invasive species took over the habitat of the yucca plant?
The moth would go extinct.
