Transcript of Research of Tropical Ocean:

Research of Tropical Ocean:
A. An abiotic factor in an ecosystem is one that is nonliving, but still has an effect on the living things within the ecosystem. The abiotic factor in the ocean would be parts that are nonliving. All other animals and plants would be the biotic factors. The abiotic factor of the ocean would be the salt, sand, and water. The salt is primarily composed of sodium and chlorine, but there might also be some nitrogen and phosphorus mixed in. The water is made up of hydrogen and oxygen atoms. Other abiotic factors in the ocean would be sunlight as well as temperature. The deeper you go in the ocean the less sunlight there will be and the temperature will also drop. This makes the conditions less favorable for the biotic factors of the ocean, and only a few specialized types of organisms would survive their. Another important abiotic factor would be Pollution. Things like garbage and oil spills can majurly affect the oceans ecosystem

Research of Tropical Ocean:
B. That some of the animals that are herbivores might fight for the plants
Research of Rainforest:
A. The biotic factors are the living things in a biome while the abiotic factors are the non-living things in the rainforest. These factors are related to each other because one has an impact on the other. Biotic factors are animaly plants, fungi, and micro organisms. Abiotic factors are water, air, soil, temperature, wind and sun. The tropical rainforests of the world are the richest source of plant life on earth. The moisture and moderate heat make it the perfect biome for an abundance of flora and fauna. The basic species in the food chain are producers. These are one-celled biotics that use abiotic factors such as solar energy to produce their own food. Consumers are biotics that rely on producers there food source. Primary consumers are herbivores. Secondary consumers are predatory omnivores who eat primary consumers and producers. These consumers have adapted and envolved in order to hunt their prey and survive in their environment. Decomposers feast on dead biotics and clean up natural litter of the rainforests. Their waste products enrich the soil, and abiotic factor. The direct sunlight warms the land and water. Evaporation is responsible for water rising, becoming vapor and cooling. Clouds cant hold as much cool water. Trees are the major form of plan life in tropical rainforests. The tall trees meet to form a canopy, blocking the majority of rain and sunlight life below it. The great expanse of the rainforests makes it difficult for reasearchers to discover and study all biotics native only to those regions.
C. Bottle nose dolphins track their prey through expert use of echolocation. They can make up to 1,000 clicking noises per second. These sounds travel underwater until they encounter objects, then bounce back to their dolphin senders, revealing the location, size, and shape of their target.
D. A symbiotic relationship is one where animals of 2 different species interact closely over along period of time. Symbiotic relationships include parasitism, commensalism, and mutualism. In a mutualistic relationshp the species benefit each other.
C. Tropical rainforests are home to move than two thirds of the world's plant species. Plants are a source of food for rainforest animals, as well as shelter. As a result of the humid, tropical rainforest environment, plants must adapt on order to survive. They also adapt in temperature forests, though not as drastically.
D. Some symbiotic relationships in the tropical rainforest include the relationship between the agouti and the Brazil nut tree. The agouti is one of the few animals strong enough to crack the nut. The tree requires the animal to spread it's seeds.
