Marine biology Flashcards
What are the characteristics of a food chain?
What eats what and the flow of energy in the ecosystem
What is the difference between a producer and a consumer?
Producer: Gets their energy from making their own food.
Consumer: Gets their food by eating living things around them.
What does the arrow direction mean in a food chain?
They represent the flow of energy. It shows the direction the energy is going in as it goes from one organism to the other.
What is the difference between a carnivore, herbivore, and omnivore?
Carnivore- A carnivore is an organism that only eats meat/ other animals. They do not eat plants
Herbivore- A herbivore is an organism that only eats plants. They do not eat animals or meat.
Omnivore- An omnivore is an organism that eats both animals and plants.
Give an example of a carnivore, herbivore, and omnivore.
Carnivore- An example of a carnivorous animal is a Walrus
Herbivore- An example of a herbivore is the green sea turtle
Omnivore- An example of an omnivore animal is a Crab
What is the difference between biotic and abiotic factors?
Abiotic factors- Abiotic factors are a nonliving element that’s in the ecosystem.
Biotic factors- Biotic factors are organisms that are either living or once lived and are in the ecosystem
Give 5 examples of biotic factors
Animals, Plants, Fungi, Bacteria, Protist
Give 5 examples of abiotic factors
Water, Soil, Air, Sunlight, Temperature
Mutualism
Mutualism is when two organisms benefit from each other
what is Commensalism
Commensalism is when two organisms come together but only one benefits, the other has none and receives no home.
Parasitism
Parasitism is when an organism has a parasite living and clinging onto them. It can be on the outside or the inside. It does cause the host some harm but not enough to kill it.
Competition
Competition in ecology is when two organisms fight for the same resources that are in the environment and required for survival.
Predator
Predator is the organism that kills and consumes another organism for food.
What is Prey
Prey is the organism that is being consumed, killed, and eaten.
An example of Mutualism
Sea anemone and clownfish.
An example of Commensalism
Sharks and Remora fish
An example of Parasitism
isopods and copepods
An example of Competition
Whale and seabird fighting for krill.
An example of Predator
Great white shark
An example of Prey
Sea slug.
Describe what ecologists study?
They look at organisms, their environment, and the behavior that the organisms do. They collect this data so they can understand the ocean better.
What does Adaptation mean?
The action or process of adapting or being adapted to different things such as your environment and prey
Three examples of adaptation
Bottlenose dolphin, Seaweed, Bryozoan colony.
An example of structural
The tube of a worm
An example of behavior
Perriwrinkles
An example of Physiological
Anemone
What is structural
Refers to the shape and structure of the organism which has been adapted to survive
What is behavior
Refers to behaviors that an organism has adopted to suit conditions eg hunting at night instead of a day.
What is physiological
Refers to the release or utilization of chemicals/toxins as a defence mechanism or as an attacking tool
Abi study the effect of temperature on the oxygen levels in rock pools at Sorrento. What’s the independent variable?
Temperature
Abi study the effect of temperature on the oxygen levels in rock pools at Sorrento. What are the dependant variables?
The oxygen levels in the pool
Abi study the effect of temperature on the oxygen levels in rock pools at Sorrento. What variables does she need to control
The water, time of day
