The question is incomplete as it does not have the options which are:
A)The concentration of sulfate in the Gulf of Mexico is sufficient for the growth of oil-degrading microbes.
B)Large amounts of iron were needed, as iron is a macronutrient for oil-degrading microbes.
C)Nitrogen gas (N2) present in air is not in a form that can be used by oil-degrading microbes.
D)The oil-degrading microbes used oil (hydrocarbons) as their carbon source.
Answer:
Large amounts of iron were needed, as iron is a macronutrient for oil-degrading microbes.
Explanation:
Bioremediation refers to a process which is performed to detoxify the natural terrestrial or aquatic habitat full of contaminated particles using the biological source like the plants, animals or microorganisms.
In the given question, the accident in the Gulf of Mexico in 2010 contaminated the aquatic body with oil so the bio-remediation technique was used to detoxify the water.
The oil-consuming bacteria were used to as bioremediation which could use the oil as a source of carbon.
The bacteria uses the support of the oxygen in anaerobic respiration and the fertilisers were added to the water to provide a source of nitrogen and iron.
The iron is used by the bacteria in its growth but it is not considered a macronutrient for the bacteria and thus is considered false.
Thus, the selected option is correct.
Answer:
plants need sunlight. (animals dont)
BOTH, plants and animals need nutrients.
BOTH, plants and animals need oxygen.
BOTH, plants and animals need a suitable temperature.
Plants and animals need water.
BOTH need carbon dioxide
The best way to reduce wind erosion on farm is to plant ground cover in unused fields.
Explanation:
- Wind erosion is defined as the removal of the top soil from unused barren land by winds.
- This results in degradation in the soil fertility and renders it unproductive.
- Roots of plants bind soil particles.
- Planting ground covers like herbs , shrubs and wild plants on unused land will prevent the exposure of the top soil to the eroding agents and reduce erosion.
Producers are organisms that make their own food. Plants would be an example. Primary consumers would be those that eat producers(plants,algae). Secondary consumers are animals that eat primary consumers. Herbivores are animals that only eat plants. Carnivores are those that only eat meat and don’t eat plants. Omnivores are those that eat both meat and plants. De composers are those that decompose organic material like dead animals. The herbivores here are the kangaroo rats,grasshoppers and bunny’s. The carnivores here are the hawk,lizard,tarantula and rattlesnake. I don’t think there is an omnivore. And the only decomposed here is the bacteria. As it decomposes the bodies of the animals when they are dead.
Because "active transport" means ATP.
