Which of the following best describes how energy is transferred in a food web?
A. A All energy is transferred to each level of a food web.
B. B Energy flows from producers to one or more levels of consumers.
C. C Consumers transfer their energy to producers.
D. D Decomposers get their energy directly from the sun.
Answer:
B.
Explanation:
Energy flows from producers to one or more levels of consumers. Think of it this way:
A banana tree grows in the forest.
A monkey eats the bananas off of the tree, it now consumes the energy provided by the banana.
(whatever animal kills monkeys) kills the money for food, they have now consumed the energy of the monkey, as well as the banana the monkey has eaten previously.
The web continues, and energy continues to be distributed to each level of consumer, all starting with a single producer.

What does an urn-shaped age pyramid represent? A. a stable population growth B. a low birth rate C. a low death rate D. a growing population
Answer:D
Explanation:
people spray pesticides on crops to kill insects that eat and destroy crops. however, these insects are becoming resistant to the pesticides. Explain how this could happen.
if a person takes antibiotics, the resistant bacteria will die. if this process continues,most of the bacteria population will have the trait for antibiotic resistance. if antibiotics are taken rarely, the population will not have time to adapt, and the bacteria will die. the more antibiotics are taken, the more chance the bacteria have to adapt and develop resistance
Since the bugs are being sprayed by the pesticides so often they start to build resistance just like how people build tolerance to alcohol. The more often the bugs get sprayed with pesticides the more they can tolerate and adapt to the pesticides.

Invasive species are one of the major threats to blodiversity. These species multiply quickly and compete with native species for food, sunlight,
space, and other resources. On the map, determine the area where native species will have limited resources available to them due to invasion.
Answer:
Top Left
Explanation:
On the map, the top-left part of North America, which is the Canada part, has the most threats due to the invasive species, which are also threats to the native species as they can easily multiply and eat the native prey.
What is an invasive species?Invasive species can outcompete native species for resources such as food, water, and habitat. This can lead to declines in native species populations, which can impact the entire ecosystem. Invasive species can alter the structure of ecosystems and disrupt natural processes. For example, some invasive plants can change the soil chemistry, while some invasive animals can alter the food web and cause changes in the behavior of native species. Invasive species can introduce new diseases to native populations, which can have devastating effects. For example, the introduced fungus that causes white-nose syndrome has killed millions of bats in North America.
Hence, On the map, the top-left part of North America has the most threats due to the invasive species, which are also threats to the native species.

Describe what the completeness or integrity of an ecosystem biodiversity is used to measure
Answer:
Disruptions to any physical or biological component of an ecosystem can lead to shifts in all its populations. Biodiversity describes the variety of species found in Earth`s terrestrial and oceanic ecosystems. The completeness or integrity of an ecosystem`s biodiversity is often used as a measure of its health.
Explanation: Disruptions can really mess with any physical or biological component of a ecosystem then that ecosystem leads to shifts in all populations. I hope this answer helps you!
The completeness or integrity of an ecosystem biodiversity is used to measure its health.
Biodiversity refers to the different types of organisms present in an
ecosystem. A healthy ecosystem is one which has a high degree of
biodiversity present in it.
High biodiversity leads to a high stability and productive rates as a result of
the high resources present. An unhealthy ecosystem has low integrity or
completeness in its biodiversity .This is why the integrity of an ecosystem
helps to measure its health.

What do many ecologists feel is necessary for an area to be classified as a forest?
a.) several species of trees
b.) enough trees to create a close canopy
c.) consistent warm weather
Answer:
B. Enough trees to create a close canopy.
Explanation:
Forests may have several tree species but one very important feature of forests is their close canopy of dense trees, often arranged in several strata (or layers).
The reason why in forests shorter trees do not survive as well as trees that reach the top of the canopy, would be light distribution and access to sunlight.
What is the use of sunlight?Sunlight must be remembered that sunlight has the vital element for the plant survival without it the photosynthesis that cannot take place, or it will not be as the efficient as it would be if there was the full access to the sunlight. Sunlight activates the electrons on the chlorophyll and with that a plant has able to produce the ATP, which has the basic energy-producing unit in any living cell.
As such in the dense forests where we have tall and the shorter, trees, those that reach the highest point of the canopy have the access to most of the sunlight, while the shorter ones have to make do with whatever filters through the branches of the others.
Thus by not having as much access to sunlight, their photosynthetic processes are not as efficient. Those that adapt to lesser amounts of light, will survive, but the others would not.
Therefore, The reason why in forests shorter trees do not survive as well as trees that reach the top of the canopy, would be light distribution and access to sunlight.

The fossil record reveals that the diversity of flowering plants and the diversity of certain insect groups increased at the same time. How might you explain this?
Answer:
Insects and flowers are connected with each other for several life purposes such as for food, habitat and pollination.
The cause of diversity in flower and insects is associated with the process of pollination. In the process of pollination, both insects and flowers are mutually get benefits.
Insects move flower to flower in search of food and in the process it also carry pollen from flower to flower as well. Through insects the pollen reaches to different flower and show diversity and at the same time insects feed on various types of flowers and reproduce generation with variations.
Hence, the process of pollination makes a relationship between flower and insects diversity at the same time.
