is a rock part of a community?
explain
no, its not alive
A shark and a remora are what type of symbiosis?
Commensalism
How much energy is reserved (doesn't move on) through each trophic level?
90%
where does life's energy come from?
the sun
what rule is there about energy concerning how much is transferred?
10% rule
is grass part of a community?
explain
yes, this is because it is alive and produces energy
a cheetah and impala are an example of what symbiosis?
predation
what is the first trophic level?
Primary producers
what are producers called?
autotrophs
Killer whale
penguin
____
algae
what is missing from this food pyramid?
fish
could humans be considered an invasive species?
explain
yes because humans usually enter environments and eat whatever they can catch which can cause extinction or cause other animals to be low in population which will mess up the food chain.
if a cow has a bird pick some ticks off of it what type of symbiosis is it?
Mutualism
how much energy would a quaternary consumer have if the primary producer had 10,000,000 energy
1,000 energy
consumers are called what, and why are they called that?
heterotrophs, because the suffix hetero means different and heterotrophs use a different type of energy than the sun (living things) and trophic means energy/nourishment
if the grass is eaten by primary consumers, and the primary consumers are eaten by secondary consumers, what eats the secondary consumers?
tertiary consumers
how do pesticides mess up food webs?
explain
they can kill some animals or cause them to be sick and when consumed by predators it could make them sick causing an imbalance in the food web causing some animals to skyrocket in population and others to die out.
a sea louse eats the fishes Toung and becomes the new Toung, it will then eat most of the food the fish catches what type of symbiosis is this?
Parasitism
if a primary producer produced one billion energy and there was 8 trophic levels in the food chain, how much energy would the top level get?
10 energy
they eat types of energy waste (roadkill)
vultures and such
what type of predator is at the top of an energy pyramid?
apex predator
if some plankton get infected with pesticides and they are eaten by some small fish, then those small fish are eaten by some penguins, then those penguins are eaten by some orcas, and the infection increases by 35% after each one is eaten. about how infected will the orcas be if each level ate 1 of everything (HINT: there are 4 levels and the infection doubles in each level)
280%
a little tree sapling has a hard time growing because of another tree, what type of symbiosis is this?
competition
catfish, eagle, snake, bear
how many of these are apex predators?
3, technically, the snake is not an apex predator in most ecosystems
5
1: herbivores (plants)
2: carnivores (herbivores and carnivores)
3:omnivores (plants, herbivores, and carnivores)
4:detrivores (roadkill and dead animals)
5:decomposers (they absorb energy from dead animals and plant matter)
are humans considered apex predators even though they could die to other animals?
Explain
Yes, humans are still top of the food chain even though that other animals can kill them.
