Answer:

At each higher level of consumption, the amount of toxin is magnified.

Explanation:

Those predators all eat smaller secondary consumers, and those secondary consumers eat the primary consumers, which a lot of the times are exposed to DDT. For example bugs are often the primary target for DDT, once those bugs are exposed to the DDT they carry it in/with them. When a fish eats the bug, that fish is now exposed to the DDT. When the fish is caught and eaten by an eagle that eagle and its young are now being exposed to DDT. The DDT might not effect the full grown eagle for its lifetime but it does effect its young.

Which statements describe Newton and the law of universal gravitation? Check all that apply.
nignag [31]

Answer:

1. Newton believed that gravity was a force.

3. The law of universal gravitation offers a mathematical explanation for the attraction between the moon and Earth.

Explanation:

Law of gravitation states that force is directly proportional to masses of objects and inversely proportional to the distance between from their center. Directly means if mass increases, force of attraction also increased while inversely means if distance decrease between objects, force of attraction is also increased. Gravity is measured in weight because weight ia a force which attracts things towards its center.

Single-celled algae and multicellular plants
OlgaM077 [116]

Answer:

<em>The correct option is A) make food.</em>

Explanation:

Photosynthesis can be described as a process by which organisms like plant and some algae make their own food. They use light energy from the sun to convert carbon dioxide and water into glucose and oxygen. Oxygen is the by- product of this reaction. Hence, option A is correct.

Other options are wrong because photosynthesis is not a process by which energy can be extracted from food or it is not a process by which excretion of waste occurs. Neither is it a process of reproduction.

Wolves feed on a variety of large prey, including elk. Elk feed on shrubs and trees like aspen and cottonwood trees.
Trava [24]

Answer:

Population size of elk increased while the population of aspen tree declined.

Explanation:

As per question, removal of wolves from the system would result in increased elk population due to absence of its predator (wolves). The increased elk population would extensively feed on  shrubs and trees like aspen and cottonwood trees. This would cause decline in population size of these shrubs and trees.
