All but one situation is an expected effect of the recent deepwater horizon oil spill in the gulf of mexico. that is: a) tar balls buried beneath beach sand influence crustacean movements, habitats, and breeding patterns. b) the rapid extinction of top-level consumers in the gulf food webs, such as sharks, dolphins, and sea turtles. c) scrubbing efforts of surrounding wetlands interfere with an areas natural ability to regenerate plant growth. d) deep sea oil plumes serve as a food source for bacteria, and in turn, the lower oxygen levels produce deep sea dead zones.

The answer is B) The rapid extinction of top-level consumers in the Gulf food webs, such as sharks, dolphins, and sea turtles.

The Deepwater Horizon oil spill in the Gulf of Mexico is the largest in the history of the oil industry. The oil spill created a large layer of floating oil patch over the gulf waters. This layer of oil blocked the exchange of gases like oxygen in the water. The top-level consumers like the dolphins, sharks and sea turtles that need to surface to breath fresh air got coated with the oil and perished.

the overall balanced equation

6co2 + 6h2o > c6h12o6 + 6o2

sunlight energy

where: co2 = carbon dioxide

h2o = water

light energy is required

c6h12o6 = glucose

o2 = oxygen

humans are now responsible for causing changes in the environment that hurt animals and plant species. we take up more space on earth for our homes and cities. we pollute habitats. human activity often changes or destroys the habitats that plants and animals need to survive.
