What is translocation in plants? ?

Biology
2 answers:
kvasek [131]3 years ago

It's really just sugars and other chemicals produced from a plant and are then transported in the <em>phloem tissue</em>. Assimilates are <u>transported</u> in sieve elements, which work closely together with companion cells to achieve translocation.

Translocation is the movement of materials from leaves to other tissues throughout the plant. Plants produce carbohydrates (sugars) in their leaves by photosynthesis, but nonphotosynthetic parts of the plant also require carbohydrates and other organic and nonorganic materials.

Natali [406]

We can confirm that the reintroduction of the wolf to the ecosystem would most likely cause a decline in the population of coyotes.

<h3>Why would this cause a decline in the population of coyotes?</h3>

The wolf, in most ecosystems, is considered to be the top predator. This means that it will also hunt and consume the coyotes. This alone would cause a decline in the coyote population as they now have an additional predator hunting them. Also, the wolves would be competing with the coyotes for food sources, furthering the impact on the coyote population.

Therefore, we can confirm that the reintroduction of the wolf to the ecosystem would most likely cause a decline in the population of coyotes.

Describe two types of living things that biologists could study. Think about types of living things that are not in the ocean —
S_A_V [24]

Answer:

Following are the two types of living things that biologists could study:

1) Animals

2) Plants

Explanation:

As we know plants and animals are the most important organisms. Animals has further categories of living things are on land:

1) Birds

2) Mammals

3) Reptiles

4) Amphibians

Fishes are not included because they are in water but not on land.

What happens to a ecosystems food chain if the concentration pollutants move up.
Furkat [3]
<span><span>Producers: Plants are producers because they make usable energy from light.  They turn sunlight, carbon dioxide and water into sugar energy.  Producers are the foundation of the food web, because they provide the base energy needed by all wildlife.</span><span><span>Primary Consumers: </span>Herbivores are primary consumers, because they receive their energy directly from plants. </span><span><span>Secondary Consumers: </span>Carnivores are secondary consumers, because they receive their energy by eating primary consumers.  Secondary consumers are predators.  An omnivore acts as both a primary and secondary consumer, because omnivores eat both animals and plants. </span><span>Decomposer:  Decomposers get energy by breaking down dead plants and animals.  They are extremely important, because decomposers convert dead matter into energy and release nutrients that can be added back to soils and ecosystems.</span></span>


<span>What is a Food Web?
</span>A <span>food web </span>is a diagram displaying how all the producers, decomposers and primary and secondary consumers interact in an ecosystem.  It shows how energy is transferred between species. 

A food web can be very simple - with one producer, consumer and decomposer- or a food web can be extremely complicated.  A food web of an entire woodland ecosystem becomes complex when you include every species from plants to insects and mammals. 


There Is More to a Food Web than Energy

When animals eat their prey, they consume more than just energy.  They also absorb all the chemicals and nutrients inside the prey.  For example, when you eat a banana you get energy from the banana, as well as the added benefits of potassium and vitamin A. 

Sometimes animals ingest pollutants that can become stored in their fat and tissues.  Human-caused pollution has added heavy metals, oil, and <span>industrial and pharmaceutical chemicals </span>to the environment.  Plants, fish and other species absorb these toxins, and as they are eaten by predators, the toxins are then absorbed into the predators’ tissues.  As the chain of predator and prey continues up the food web the toxins become more concentrated and move higher and higher up the food web.  The pollutants can have a disastrous effect on the food web and potentially kill species.


What happens when a Chemical is Added to the Food Web? 
To explain the true impacts of chemicals on the food web, we’re going to use the real world example of mercury poisoning. 

Coal-fired power plants burn coal and release mercury into the atmosphere as a byproduct.  Over time, mercury falls to Earth through rain, snow and natural settling.  Rain carries the mercury to streams and rivers and it eventually settles in lakes and ponds. 

After mercury enters lakes and ponds, bacteria transform mercury into a more easily absorbed toxic substance called methylmercury.  Aquatic plants, bacteria and plankton absorb methylmercury from the surrounding water. 

It’s at this point that mercury becomes added to the food web.  Eventually, the contaminated plants, bacteria and plankton will be eaten by predators, such as fish.  The methylmercury toxins will move into the tissues of the fish and poison a new level of the food web. 


Magnifying Up the Food Web 
Individual plants, plankton and bacteria only have a small amount of methylmercury.  The problem begins at the next level of the food web.  Fish don’t eat just one plankton or plant – they can eat hundreds or thousands of them!  All the mercury in each of the plankton or plants has now been eaten by a fish and absorbed into the fat and tissues.  After eating 100 plankton, the methylmercury in the fish is now 100 times what it was in the plankton! 

It doesn’t stop there.  The higher and higher up the food chain you go, the more food is necessary to maintain energy and activity. 

<span>If a small fish eats 50 mercury contaminated plants.And a large fish eats 100 small fishAnd an eagle eats 100 large fish.</span>

50X100X100 = 500,000  The concentration of mercury in the eagle is 500,000 times larger than it was in the plankton!!

The process that causes the concentration of a substance to increase as it moves up the food web is called bioaccumulation.  Methylmercury is a famous example of bioaccumulation, because mercury poisoning causes neurological disorders, reduced reproduction and even death in raptors and mammals.  People are susceptible to mercury poisoning by eating too much contaminated fish.  

Study the diagram to see how mercury bioaccumulates up this common food web.
