Kelp Forests And Coral Reefs Flashcards
Identify the parts of kelp
Blade, gas bladder, frond, stipe, holdfast
What is a kelp forest
They are underwater areas with a lot of kelp and they cover most of the worlds coastlines. And they live in shallow cold water
Why are kelp forests diminishing
Climate change/ocean warming and sea star wasting disease
What is the difference between a behavioral adaptation and a physical adaptation
Physical adaptations help animals survive in their environment. Examples include camouflage and mimicry. Behavioral adaptations allow animals to respond to life needs. Examples include hibernation, migration, instinct, and learned behavior.
What are the 3 main types of algae
Green, brown, red
How is algae classified
Color shape location
Which tide zone does algae grow in
Intertidal zone of rocky shore lines
What determines what algae type grows where
Light, temperature, mixing and nutrients
Which food and products are seaweed, algae, and kelp found in
Jam, Ice cream, sauces, salad dressings, toothpaste and pet food
What is a coral reef and what are the components
They are made up of a bunch of tiny polyps. And are made up of thin layers of calcium carbonate and they are in warm water
What are the 3 types of coral reefs
Fringin, barrier, atoll
Define the 2 types of coral
Hard coral - stony and as hard as a rock.
Soft coral - is bendable
Why are coral reefs important
They protect coastlines from storms and erosion. They provide jobs for people. They are a source of medicines.
What is the skeleton of coral made of
Calcium carbonate
Describe the relationship between corals and zooxanthellae
Zooxanthellae live in the corals polyps and help the coral survive by providing it with food resulting from photosynthesis and then the coral provides a protective environment for the zooxanthellae
What are some causes of coral reefs diminishing
Climate change, overfishing, pollution
What are some things we can do to help protect coral reefs
Avoid touching the reefs when in the ocean. Wear a reef friendly sunscreen. Don’t throw trash in the ocean.
What is meant by coral bleaching
It’s when the coral turns white and this happens by the rising temperature caused by climate change
What is ocean acidification
A reduction in the ph of the ocean over a extended period of time. Caused by to much Co2 in the atmosphere.
How are coral reefs and kelp forests alike and how are they different
They both provide protection and a home to organisms. And kelp forests are found in cool shallow waters and coral reefs are found in warmer waters.
What is a sponge
They are animals with dense skeletons that are highly adapted to their environment
What is a spicule
It’s the sponges skeleton and it protects them
How do sponges eat
They use filter feeding
How do sponges reproduce
By budding and they reproduce asexually and sexually
How do sponges move
They sink there spicules into the ground and pull on them to haul their bodies forward
Why are sponges important
They provide a habitat to species. And they make the water cleaner. And they produce carbon.
Why do coral reefs and kelp forests need sea urchins
Because they feed on dead organisms and they maintain the balance between coral and algae
What are some behavioral adaptations of sea urchins
They have sharp hard testy to scrape algae off rocks
What are some physical adaptations of sea urchins
They have a mouth with a sharp beak
