Tropical Ocean and Tundra
 Tundra: We did our project over the Tundra and Tropical
Ocean. The symbiotic relationships were polar bears and
caribou. Another is polar bears and seals. The predator-prey
relationship is snowy owls and lemmings. The competition is
between polar bears and artic wolves for resources. A limiting
factor in the Tundra is the lack of food makes it hard for
herbivores to survive, such as the musk-ox, which explains
why few species live there. Some other factors are
temperature, rain, wind, permafrost, and altitude. The
temperature in the tundra is what makes it the coldest biome
in the world. It has little rain year round. It has long winters
and short summers.
 Tropical Ocean: Our next ecosystem was Tropical Ocean. A
symbiotic relationship clownfish and anemone. Another
sharks and remora. A predator-prey relationship is conger eel
and wrasse. Some competition is deep water angler fish
compete with each other. Some limiting factors are
temperature, current direction, velocity, and the runoff from
land. Some more are viral disease, predation, parasitism, and
competition.
