Transcript of Beach ecosystem
ticks (ticks are on most of the birds at the beach. They are around the birds eye) Abiotic Factors What are abiotic factors? Abiotic factors are non-living factors in the environment. Physical or chemical. Abiotic factors at the beach are:
sand- used for shelter
rocks- used for shelter
shells-depends on size but could aslo be used as shelter What is a beach? A beach is a sandy shore that is by the sea between high- and low-water marks. This is a terrestrial ecosystem. A terrestrial ecosystem is found on a land form.
At the beach there are many abiotic and biotic factors. Beach food web What's what? Biotic factors have 6 relationships that are applied to. These relationships are producers, consumers, predators,prey, parasite, and host. Bibliography Marine Biology Project. (n.d.). : Abiotic and Biotic Factors in the Intertidal Zone.

Retrieved from http://water.epa.gov/learn/kids/beachkids/what-beaches.cfm Competition There could be some competition at the beach.
-The mole crabs and the ghost crab fighting each other for food.
-The crabs could fight for shelter.
-The frog and the seagulls fighting for flies.
-Worms and frogs could fight for shelter
-A jellyfished washed up on land would fight a crab for water. Symbiosis Commensalism- A worm would hide in the sand from prey. The sand is not harmed but the worm gets shelter. Mutualism- A bee and a flower. The bee gets the nectar from the flower while the flower can reproduce. Neither is harmed, they are both helped. Parasitism- A tick and a bird. The tick is the host and the bird is the parasite. The bird is harmed and the tick is helped and not harmed.
