carrying capacity and changes in population
the carrying capacity of a biological species in an environment is the maximum population size of the species that the environment can sustain indefinitely, given the food, habitat, water, and other necessities available in environment. everything in the aquatic ecosystem need each other no matter if it's abiocyoc or biotic. Predators need the pray, both need the water. They all need each other to work together and survive.
The population changes over time by one organism consuming another one, each organism eventually dies one way or another.
limiting factors: the factor that limits the reaction rate in any physiological process government by many variables.
predator: shark prey: seal
A shark relies on meat, like seals, to survive. Some limiting factors of an aquatic ecosystem are: water temperature, sunlight, amount of nutrients, and dissolved oxygen content.
Energy Roles Producers- plants are the first level in the food chain or food webs; kelp, phytoplankton, algae, coral, and mosses
Herbivore- an animal or person that only consumes plants; green sea turtle, marine iguana, and manatees
Omnivore- An animal or person that only consumes both plant and animals.; seal, killer whales, and dolphins.
Carnivore- An animals, or occasionally a person, that consumes only meat; shark, leech, piranha, and alligators.
decomposers- an organism, especially a soil bacterium, or fungus, that decomposes organic material; bacteria, marine worms, echinoderms, and fungi
scavenger- an animal that feeds on carrion, dead plant material, or refuse; shrimp, dungeness crab, and lobsters.
food chains vs food web food chain is one producer, one primary consumer, one secondary consumer, and one tetirary consumer. A food web is more than one producer and all of its consumers spread out, and then the primary consumers predators and then on going.
Tropic Levels and Energy Pyramid
this picture shows the different levels of the aquatic ecosystem. The producers, the herbivores, and the carnivores. It shows how the herbivores have to consume the producers, and the carnivores consume the herbivores.
producers at the bottom of the pyramid, because it is what produces the energy to convert it the organisms that consume it.
