biotic and abiotic factors Flashcards
what is a biotic factor

what is a biotic factor in the great barrier reef
stingrays preying on mollusks for food
sponges and coral competing for space
black band syndrome eating away at coral tissue
what is an abiotic factor in the great barrier reef
the average water temperature of 29 degrees
the sunlight intensity
the pH or acidic levels in the sand
conservation status
near threatened
native or introduced
native/
3 superpowers
- camouflage abilities
- creating their own body double from a cloud of ink
- change colours to match their environment even though they are completely colourblind
major threats
habitat loss and pollution
impact if they disappeared
Cuttlefish are animals that impact the food web greatly, without them there would be great impacts on the apex predator numbers and the overall marine ecosystem.
how to protect
ban fishing in the great barrier reef and protect its habitat (the Great Barrier Reef) by doing routine checkups on the reef and acting according to the results.
producers
make their own food:
seaweed, seagrass, coral
consumers
eat other organisms to gain energy: cuttlefish, clownfish, turtles
apex predators
top of the food chain/web:
tiger shark, bull shark, hammerhead shark
decomposers
break down organisms to recycle nutrients: fan worms, bacteria, snails
trophic level
secondary consumer
