The ocean controls the weather. It also provides a habitat and nutrients for many organisms and microorganisms. The ocean is a critical part of the ecosystem.
My inquiry question
How do biotic and abiotic elements in and around the ocean affect each other and certain man made elements in our ecosystem?
Sardines go to the shallows to feed on phytoplankton. Predators such as sharks,cape gallons, and dolphins, follow the sardines.
Extreme weather conditions (such as floods, heat waves and high winds) have a very well know negative impact on city environments. Cities, tend to be warmer the other environments. Climate change could make the heat waves in the cities even warmer, this would increase the amount of energy that we use during the summer for air conditioning. Which would increase the amount of air pollution and the greenhouse gas emissions from power plants. Flooding and high winds promote the usage of portable electric generators, which contribute to carbon monoxide poisoning.
Phytoplankton is very important to the underwater ecosystem. At night certain organisms/micro organisms ascend from the depths of the ocean to feed on phytoplankton. They are followed by predators, then they all return to the depths of the ocean at dawn. There is a sudden bloom of phytoplankton in the spring.
Herrings, which are a species of fish, come to Alaska to breed, each female lays aroud 20 thousand eggs each. they lay eggs at a specific time because the hatchlings will feed on the bloom of phytoplankton in the spring. A lot of animals come to feed on the Herring eggs including: Grizzly bears and Surf birds.
After the dolphins chase the sardines into the diving range of the cape gallons, they dive into the ocean to feed on the sardines.
Grey whales come to Alaska to feed on plankton, after the herrings leave. The mother has to stay with her calf. When killer whales attack the mother tries to hurry her calf to protect it. When it gets tired they stop, allowing the killer whales to attempt to drown the calf, she tries to keep it from drowning, unfortunately she is unsuccessful.
The weather affects how much energy schools use.
The ocean controls the weather.
The ocean provides a habitat and many sources of nutrients for sardines.
Dolphins consume sardines to obtain nutrients.
Dolphins play a big part in the sardine rush. They chase sardines to the surface so they have no more escape from the cape gallons. Dolphins use bubbles to trap the sardines. The sardines are now in more compact groups making it easy for sharks to consume them.
The location of a school has a large impact on the environment. If students have good sidewalks and neighborhoods they're more likely to walk or bike to school. Schools use a lot of water, it is used for activities such as: cleaning, drinking, and restroom purposes. Schools also use a lot of energy for: heating, cooling, and lighting classrooms and hallways.
The sardines are now in more compact groups making it easy for sharks to consume them.
“Sharks seem to get very excited whenever dolphins are around. Most likely because they know they’re about to feed very well, because the sardines are in more compact groups near the surface.”
Dolphins make the sardines into more compact groups so it's easier for sharks to consume them.
The dolphins chase the sardines into the diving range of the cape gallons.
(Sardines consuming phytoplankton)
Killer whales spot a mother grey whale with her calf. They plan to eat the calf, they trick the mother into hurrying along her calf, when the calf gets tired they separate it from it’s mother. The killer whales now attempt to drown the calf by jumping on it, the killer whales take turns jumping on the whales now that the mother whale is underneath her calf. Eventually they kill the calf and eat only the lower jaw and tongue.
Hagfish and Sleeper sharks
Decaying whale carcases sink to the bottom of the ocean, hagfish feed on the whale carcases. Hagfish are very primitive organisms, they’re not really fish. Sleeper sharks also feed on the whale carcases at the bottom of the ocean.
Sardines consume phytoplankton to obtain nutrients.
The herring eggs will eat phytoplankton when they hatch.
The ocean provides a habitat and sources of nutrients for grey whales.
Killer whales eat the tongues and lower jaws of grey whale calves.
The hagfish and sleeper sharks eat the decaying whale carcases.
