I take that the insects remain constant no matter what happens to the frogs (which the frogs eat presumably). So a constant food supply for the frogs is not the problem.

The line for the alligators increases over time. It their numbers increase, the frogs are in trouble. The alligators will pursue lunch with determined single mindedness and there are more of them around.

So the frogs should decrease. Their natural enemy is the alligator and alligators won't go after insects. It's not worth their time.

A is the only answer you can choose.

A helium balloon has a volume of 2.00L at 101kpa. As the balloon rises the pressure drops to 97.0kPa. What is the new volume?
Mrrafil [7]

Answer:

2.08L

Explanation:

V1 = 2.00L

P1 = 101kPa

P2 = 97.0kPa

V2 = ?

from Boyle's law,

P1V1 = P2V2

101 × 2 = 97 × V2

V2 = 202/97 = 2.08L

Therefore, the new volume is 2.08L

Several tomato plants are grown indoors next to a sunny window. The plants receive water and fertilizer and remain on the window
mrs_skeptik [129]

You can see my previous answer to this very same question on brainly.com/question/11374210.


The answer is:  option D. Response to environment.


Explanation:


As explained, plants (organisms in general) respond to the stimulus provided by the environment.


Such behavior is named tropism. Tropism may be positive or negative.


When the plant's stem bends toward the window, it is showing positive phototropism, which means that the plant growth response to light such that the stems bend toward light, permiting the leaves to receive more light.


I also mention that while the plant's stems posses positive phototropism they posses negative gravitropism and the roots posses positive gravitropism.


Gravitropism is the response of the plant growth to gravity.


Stems grow away from gravity meaning that this is negative gravitropism, but roots grow toward gravity which is positive gravitropism
