Ecology Extras • Growth of photosynthetic organisms because used CO2 in photosynthesis to make food • Nitrogen is required to make amino acids (building blocks of proteins) 6. Thousands of acres of tropical rainforests are cut down each year, primarily for farming and wood products. Identify two negative environmental consequences of rainforest destruction. Explain the negative impact of each consequence. (4 points) Write the answer on separate paper. Scoring Guidelines index Bioaccumulation and Biomagnification • Bioaccumulation- how pollutants enter a food chain • Biomagnification- pollutants tend to concentrate as they move from one trophic level to the next. You’ve found your niche! • Ecological niche- the role and position a species has in its environment – Habitat- where an organism lives • No two species can occupy the same ecological niche at the same time if resources are limiting… Relationships • Symbiosis: is a close ecological relationship between the individuals of two (or more) different species • Mutalism: both species benefit • Commensalism: one benefits, one unaffected • Parasitism: one benefits, one harmed • Competition: no one benefits Phylogenetic Tree
