in what generation does this population reach its carrying capacity
Answer:
The logistic population growth happens as the growth rate declines as the population exceeds the carrying power. The highest number of people in a community that the ecosystem can sustain is carrying capacity.
Explanation:
A population may reach its carrying capacity in any generation, depending on a variety of factors such as the availability of resources, predation, competition for resources, and other ecological and evolutionary processes.
What is carrying capacity?The carrying capacity of a population is the maximum number of individuals that can be supported by a particular environment over a given time period. A population may reach its carrying capacity in any generation, depending on a variety of factors such as the availability of resources, predation, competition for resources, and other ecological and evolutionary processes.
For example, if a population of animals is introduced to a new habitat with abundant resources, it may be able to grow rapidly and reach its carrying capacity relatively quickly. On the other hand, if the population is facing competition from other species or is subjected to predation or other limiting factors, it may take longer for the population to reach its carrying capacity.
It's important to note that the carrying capacity of a population is not a fixed value, and it can change over time due to changes in the environment or the population's own characteristics. For example, if the population grows to a size that exceeds the carrying capacity of its environment, it may begin to experience negative impacts such as resource depletion, disease outbreaks, or other factors that can reduce its size and bring it back down to the carrying capacity.

The bright color pigment of some frogs is processed as a warning to vampires. This chemical defense is understood as poisonous.
What is Chemical defense?
These bright colors serve as a warning to predators: "Don't consume me; because it is poisonous." In this consideration, frogs aren't overhead bluffing.
Some nonpoisonous species of frogs have assumed the colors of poison dart frogs to trick vampires into offering them an expansive berth they don't earn.
This technique is prompted by melanin, a dark pigment. These frogs usually combine in with their surroundings and their skin functions as camouflage.

Explanation: is correct
green and yellow wavelengths of light are not useful to most plants.
The statement that green and yellow wavelengths of light are not useful to most plants is incorrect. In fact, green and yellow wavelengths of light are essential for plant growth and photosynthesis.
Plants primarily capture light energy for photosynthesis using specialized pigments called chlorophylls, which are most efficient at absorbing light in the red and blue regions of the spectrum. As a result, the green wavelengths of light are reflected rather than absorbed by chlorophyll, giving plants their characteristic green color.
While it is true that green light is less absorbed by chlorophyll compared to other wavelengths, it still plays a vital role in photosynthesis. Green light is still partially absorbed and contributes to energy transfer within the plant, helping drive the photosynthetic process.
Moreover, certain types of plants, such as shade-tolerant plants or plants adapted to low-light conditions, have chlorophyll pigments that are more efficient in capturing green and yellow wavelengths of light. These plants can utilize a broader range of light wavelengths for photosynthesis, including green and yellow light.
Therefore, green and yellow wavelengths of light are indeed useful to most plants. While red and blue light are more efficiently absorbed, green and yellow light still contribute to the energy needs of plants and play a role in photosynthesis.
