Vocabulary
This is the “Variety of all types of organisms living in a given area”
Biodiversity
the organism that hunts others and feeds on other living organisms.
Predator
Living organisms Ex:(dolphins, oysters, shark, fish, crabs, coral, seaweed, algae)
Biotic factors
If you had a 4 level energy pyramid and the producers started off with 5000 joules of energy. How much amount of energy does the first trophic level have?
5000 joules
This model shows how a series of energy moves from producers to different levels of consumers in an ecosystem
A food chain
The ZONE in a body of water that does NOT receive light and usually has fish with big eyes, sharp teeth, and wide mouths.
Aphotic zone
What organisms are generally at the base of a energy pyramid and are known as autotrophs?
Producers
The zone in the water where there is the most biodiversity and involves photosynthesis. (Hint:there’s light)
Photic
If you had a 4 level energy pyramid and the producers started off with 5000 joules of energy. How much amount of energy does the fourth trophic level have?
5 joules of energy
These organisms feed on dead material and helps producers grow.
Decomposers (Fungi and Bacteria)
the amount of salt in a body of water
Salinity
How much percent of energy is transferred from one trophic level to another trophic level
10 percent
In aquatic ecosystems several organisms rely on each other. If there is a decrease in the amount of dissolved oxygen what will happen to the biodiversity in the aquatic ecosystem?
Decrease in populations from several aquatic organisms. Decline in biodiversity.
If you had a 4 level energy pyramid and the producers started off with 700 joules of energy. How much amount of energy does the third trophic level have?
7 joules of energy
What process helps producers grow and what are 3 main things it needs to function.
Photosynthesis: Sunlight,Water, CO2,
Non-living. Ex: (water, temperature, wind, salinity, pH, sunlight)
Abiotic factors
Out of producers, primary consumers, secondary consumers, tertiary consumers which receives the least amounts of energy?
Tertiary consumers
Give me 3 different biotic factors in a aquatic system(lake, ocean, pond, river)
3 living things in any aquatic system
If you had a 5 level energy pyramid and the producers started off with 15000 joules of energy. How much amount of energy does the 5th trophic level have?
1.5 joules of energy
In a food chain, this level contains organisms that eat producers.
Primary consumers
A process in bodies of water where algae grows too big from nutrients. Later decreasing oxygen levels in the water and causing living organisms populations to die due to lack of oxygen.
Eutrophication
What are consumers and organisms that feed on other organisms for energy and nutrients known as
Heterotrophs
Give me 2 abiotic factors in the aphotic zone of any body of water.
Temperature, Water pressure, Darkness, chemosynthesis, hydrothermal vents, plumes,
If you had a 4 level energy pyramid and the producers started off with 400 joules of energy. How much amount of energy does the 4th trophic level?
0.4 joules of energy
This type of consumer eats both plants and animals and can play more than one role in a food chain
Omnivore
