Artificial reefs are naturaly made in the ocean, true or false.
false, they are man made structures that grow off of inhabited ocean life.
What is the definition of decomposer?
Decomposers are when an organism breaks down.
Describe the definition between food chain and food web.
Food chain- linear links of food levels.
Food web- interconnection of food chains.
The top of the energy pyramid belongs to the _______.
apex predators.
an example of predation is...
a lion hunting a rabbit.
What are some things artificial reefs grow best off of?
concrete, steel, rocks, old ships, train cars, and other eco-friendly materials.
Producers are an organism that _________.
What is an example of a food chain?
A shark eats a big fish, the big fish eats a little fish, and the little fish eats seaweed.
What is the 1st trophic level on an energy pyramid?
producers.
What are the 4 types of symbiosis?
mutualism, predation, commensalism, and parasitism.
why are artificial reefs GOOD in the ocean?
help restore and create new habitats for marine species to thrive.
Herbivores are plant only consumers. True or false.
True.
What is the definition of food chains?
A food chain is a linear network of links in a food web, often starting with an autotroph, also called a producer, and typically ending at an apex predator, detritivore, or decomposer. It is not the same as a food web.
What is the definition of energy pyramids.
An ecological pyramid is a graphical representation designed to show the biomass or bioproductivity at each trophic level in an ecosystem.
What is the difference between parastism and predation?
Predation is when one is being hunted and parasitism is where one is harmed from a parasite.
why are artificial reefs BAD for the ocean?
if artificial reefs are not carefully planned or constructed, they can actually damage natural habitats.
What is an example of a detritivore?
Earthworms, millipedes, dung beetles, fiddler crabs and sea cucumbers.
What is the definition of food web?
A food web is the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community.
What is the name of the 4th tropic level in an energy pyramid?
Tertiary consumers.
Describe each type of symbiosis. (mutualism, predation, commensalism, parasitism.)
mutualism- both benefit.
parasitism- one is harmed and one benefits.
commesalism- neither is harmed but one benefits.
preadation- one is harmed and the other benefits.
About how much pounds of plastic is in the ocean?
83,775,659,630 or just 83 billion.
