My Home Biome

Seahorses live in tropical or temperate seagrass beds, coral reefs, mangroves, and estuaries across the Atlantic from Nova Scotia to South America.  In coral reefs, seahorses live in typically tropic or subtropic oceans, in shallow areas of water.  Seahorses live in a coral reef, so they live amongst corals, and small animals such as plankton, and coralline algae is common amongst most coral reefs.  Plankton are tiny animals that live in warm shallow waters, the revolutionary advantage that keeps plankton alive is that they reproduce faster then they can be consumed by predators.  Coral are plant-like animals, they stay in one place, they eat plankton and get some of their energy from the Sun.  Coralline algae grows on the Coral and other parts of Coral Reefs, as the water is warm and receives a high amount of sunlight.  The biggest issue facing coral reefs is that coral reefs are dying; overfishing, pollution, and coral mining are causes of the decay of coral reefs.  General protection of coral reefs will help prevent their decay and death, this would entail limiting the amount of pollution entering the reefs, and the prevention of overfishing.  Seahorses do not seem to have a specific niche, they are secondary consumers who eat small animals, seahorses' main purpose in life is just to reproduce.  Seahorses are interesting in that the males will receive an egg from a female where it is fertilized and incubated in a pouch on the male seahorse.  The general food web of seahorses is something like what is shown in the following image

Tuna are known to eat seahorses during the times of year when food is scarce and seahorses are easily preyed on as they are not strong swimmers and lack natural defenses.  There does not appear to be a niche overlap, just predation of a species.

Furnace Brook Lab Report

Hey! Totally check out my sick lab report.  It took me like 5 hours.  Why does anyone do IB?

Biomagnification Case Study

Biomagnification is the concentration of toxins (such as DDT) in an organism that is a result of accumulation and concentration of it ingesting plants or animals where the toxins are more widely dispersed.  The level of toxins will become more concentrated the higher level the organism is.  The top predators in a food chain will have the highest concentration of toxins.  DDT was initially made and used to be a insecticide to help prevent the spread of: malaria, typhus, as well as other insect-borne diseases in civilian and military populations.
This toxin is spread through the food chain very easily.  The insects will ingest DDT through producers such as plants.  The DDT will be stored in fat cells and next level predators will eat the insects, and thus eat the DDT as well; which will also be stored in their fat cells.  This will result in a higher concentration of DDT in the secondary consumer, as they will be eating more food with DDT in it.  Then the tertiary consumers will eat the secondary consumers, and will result in an even higher level of DDT.  An example of this is as follows: DDT is sprayed in a marsh to control the mosquito population.  This will cause trace amounts of DDT to be stored in plankton, filter-feeders such as clams and some fish will eat the plankton causing an increase in the concentration of DDT.  Then, predators such as gulls will prey on the filter-feeders.  Since then the world governments have largely stopped using DDT all together.  The World Health Organization (WHO) in September, 2006 declared its support of using  DDT indoors in African countries in which malaria is a major health problem.  Regardless, DDT is largely unused today, as it poses a serious risk to both the health of ecosystems and humans.
