|
What is an ecosystem?
An Ecosystem is all the living and nonliving things in an area

|
Where do competition and symbiotic relationships take place?

|
Where is the greatest amount of energy located in an energy pyramid?

Organisms may compete for space, water, light, food, or mates.
|
Complete this sentence: Decomposers eat ______ or dead organisms.
Decomposers eat waste or dead organisms
|
Complete this sentence: Almost _______ of Earth’s atmosphere is nitrogen gas Compare and contrast the Matter cycle and the Nitrogen Cycle.
Almost 8/10 of Earth’s atmosphere is nitrogen gas

Compare and contrast the Tundra biome and the Grassland biome.
The Tundra is the coldest of the biomes; the average temperature in the tundra is around -18 degrees.
Grasslands are biomes that are covered with many types of grasses and have few trees. |
Compare and contrast freshwater and saltwater.
Freshwater bodies of water contain a very small amount of salt; the water is fresh.
Saltwater bodies of water contain a large amount of salt. |
Compare and contrast symbiosis and parasitism.
Parasitism is the relationship in which one organism benefits and the other is harmed. It is an example of symbiosis.
Symbiosis is a long-term relationship between different species in which at least one species is always helped |
Compare and contrast a food chain and a food web.
A food chain shows how energy passes directly from organism to organism.
A food web is made up of many food chains. |
Compare and contrast the Matter cycle and the Nitrogen Cycle.
Almost 8/10 of EartIn the Matter cycle, decomposers change the wastes and dead material into minerals and nutrients. On the other hand, in the Nitrogen cycle, bacteria changes the nitrogen into nitrate, what plants can absorb.
In both cycles, plants absorb something. |

|
Predict: Predict what would happen to a plastic bag when it is dropped in freshwater and saltwater. Does plastic help or hurt our water ecosystems?
Plastic will float in either body of water.

Predict: Predict what would happen to an organism if it cannot compete.
The organism may die or may be forced to move away.
|
Predict: Predict what would happen if we kill every plant or producer.
If we kill every plant or producer, herbivores or any other consumer would not have food to eat. This would lead to the death of herbivores
|
Predict: Predict what would happen to nitrogen levels if lightning did not exist?
If lightning did not exist, fewer nitrogen compounds would be available to move through food chains.
