The ocean biome #ecosys5
- Killer whales water temperature
- green sea turtles amount of sunlight
- the coral reef seashells
- sea grapes sand
The large number of species that the environment can support.
The resources needed for the killer whales to survive is their prey,oxygen,and sunlight
Evolution of the killer whales
Killer whales need oxygen even though they live under water but the killer whales had gained a adaptation,their blowholes.That allows them to swim under water while holding their breath for periods of time,then they'll go to the surface to get more oxygen and blowing out the water they had swallowed.
Environmental conditions that limits the growth abundance,and distribution of an organism in any ecosystem.
Great white sharks hunt their prey,Green sea turtles and that helps keep the two species population balanced.Sometimes weather could throw the balance off by the climate.The weather could get colder causing the water temperature to drop and some of the sea plants to die out. Green sea turtles herbivores and when the plants die out soon the sea turtles will too from the lack of food.Great white sharks would starve or go into competition on hunting another prey.
The amount of energy being passed on to one organism to another.
Producers: seaweed,algae,sea grass
Herbivore Consumers: sea turtles,clown fish, manatees
Carnivore Consumers: dolphins,jellyfish,hammer-head shark
Omnivore Consumers: saltwater crabs,sea lions,sea otters
Decomposers: shrimp,hag fish,ocean's fungi
Each organism recieves their energy from the organism they had consumed besides the producers because they can make their own food.
Producers start all food chains,webs,and pyramids.Producers are important because consumers get their energy from the producers and from the animals that eat the producers.
Food webs show many different consumers,and different interactions with the organisms.The marine food webs show how the energy flows form each organsims to another.
If the algae were to be remove,the krill's population would decreased because krill are herbivores and their diet is algae.The krill would probably have nothing else to eat,so their population would decreased.The krill's predators would have to find a new source of food.
Each level of the pyramid shows how much of the energy is being transfer to to the organism.Each trophic gets smaller because less energy is being passed on to that specific organism.
base and the top levels
Producers are the largest trophic level because producers don't eat other organisms to get their energy,they can make their own food by the sun's energy called photosynthesis.The top predators get their energy by consuming other organisms and the animals that eat plants causing the top predators too have less energy.
What is needed for photosynthesis is sunlight,water,and carbon dioxide.The products that the plant produces are oxygen and glucose (food).
Energy transformation in photosynthesis
A turning or bending movement of a plant toward or away from the the external stimulus. (light,gravity,heat
If sea grass was growing toward the sun,moving where ever direction the sun goes,it'll bend toward that direction which is phototropism.
Another example would be is if algae were to grow on a rock then that is thigmotropism because the algae is growing upward to the sun to get it;s energy.
If the sea grass didn't bend in the direction the sunlight is,then the grass might die because they need the sun's energy to do photosynthesis.
Decomposers are important because they break the dead to make nutrients for the plants to use to help grown and store the nutrients needed.If there were no decomposers then there would be a lot of waste,which could pollute the water causing many animals to die.
Fungi, starfish,sea slugs,marine worms.
Adaptations are important because organisms have adapted to their environment so they get new abilities to help them survive in a specific to that ecosystem.Cats' paws are specificly made just the way they are because cats use them to paunce on their prey.
What plants and animals need to survive in our environment would be that animals need the ability to hunt so they could catch their prey,and plants would need to know how to store food for the cold months.
If an organism were to be switched to another environment then it would have to adapt to that specific environment and gain new abilities to survive.If you put a starfish in fresh water then the starfish would have to adapted to the fresh water since starfishes live in saltwater.
The process of living organisms that are better adapted to the environment they live in are better to reproduce than the organisms that don't adapt to the environment as good.
Natural selection is important because if an organism didn't adapted to the environment they are living in very well then the species would have a hard time reproducing and having population growth.
An example dolphins and other whales were naturally selected by having a blowhole.The whales and dolphins are mammals and only breathe in oxygen but since they live in water,they had adapted to living under seas than to on land.They envolved to get a blowhole allowing to hold in their breaths long periods of time,and come up to the surface to get more oxygen.
