What are the current threats to biodiversity?
The earth is the home of all living creatures belonging to different species. This is a fact, one which is quit evident. The earth is being so badly misured and exploited everywhere, that it may case before long to serve as our home. The eco-system deals with the inter-relationship of the living organisms withtheir environments This natural balance between the living beings and their surroundings is threatened by the actions of man and to this extent the eco-system is threatened. There are many types of threat to the earth some of them are : 1) The distruction of the tropical rainforests: These forests produce the maximum oxygen the earth and by obsorbing sunshine it regulates the global temperature.In past some years
Is there one ecosystem that has the highest amount of biodiversity?
i don't know that is why i needed to find out can someone help me please. <3
What are decaying organisms in the soil?
All living things use reduction reactions in some form, even plants whose main contribution to the food chain is the formation of simple carbohydrates. When sunlight is not available for photosynthesis, plants metabolize (oxidize) these products for energy.
Why India called the mega diversity nation of the world?
India falls on tropical & subtropical zone where rainfall, sunlight & temperature is optimum.
What is the impact of industrialization on biodiversity?
clearing of land for construction of huge building effect the small habitat's, in different ways. such as lose of food, shelter mention but few.
What are the major causes of biodiversity loss and their impact on environment?
Always remember the acronym C.H.I.P.O
- Climate change
- Habitat destruction
- Invasive Species
- Pollution
- Over exploitation
The main causes of loss of biodiversity are:
- Increase in population
- Industrialization and urbanization.
- Overgrazing
- Pollution of air, water and soil
- Habitat destruction
- Hunting and killing of animals
What molecule initially binds with carbon dioxide in the Calvin cycle?
The initial molecule that binds with carbon dioxide in the Calvin cycle is ribulose-1,5-bisphosphate (RuBP). This reaction is catalyzed by the enzyme ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO).
What are the disadvantages for not having a backbone?
you will probably find yourself in a wheelchair for the rest of your life eating oat meal and depressed
Why is the biodiversity of plants important?
The biodiversity of plants is important for maintaining healthy ecosystems and providing essential ecosystem services such as carbon sequestration, oxygen production, and water filtration. It also contributes to food security, as many plants are sources of nutrition for humans and animals. Additionally, plant biodiversity plays a crucial role in supporting biodiversity of other organisms and ecological processes.
What are the substances used Calvin cycle?
The Reactants for the Light-Independent Cycle(Calvin Cycle) are ATP, CO2, and NADPH
Why do some biomes have greater biodiversity than others?
It all depends on the nutrients of the soil. Different plants require different nutrients, this is why farmers rotate their crops.
What everyday use do you make of taxonomy?
There is are several everyday uses of taxonomy. This is what helps with the identification and naming of organisms that we encounter daily.
How do I draw a food web for a king cobra snake?
To draw a food web for a king cobra snake, start with the king cobra at the top of the chain as the predator. Then, list the animals it eats, such as rodents, birds, and smaller snakes. Next, include the organisms that prey on the king cobra, such as large birds of prey or other predator snakes. Connect these organisms with arrows to show the flow of energy in the ecosystem.
What is a mammals ecological niche?
The extinct dog-like mammals are from a biological family of carnivorous mainly called Canidae. The Canidae includes almost 34 species from the manned wolf to bush dogs (short in length).
False. The loss of a species from an ecosystem can have cascading effects on other species and the overall balance of the ecosystem. Each species plays a specific role in the ecosystem, so the loss of one can disrupt the interconnected relationships within the system.
Why do we need to conserve biodiversity?
2. Because God made the world and everything in it, and gave it to man to cultivate, care for and protect. (spiritual version)
3. Because there are still so many species we have not yet even found. Many of these still being discovered have and will yielded volumes of information about our world and cures for our ailments. The most resent discoveries have advanced our ability to fight cancer. (humanitarian version)
4. Because Biodiversity is declining and we need to understand why, how it is going to effect us all, if we are causing it or if we can afford to help maintain it, and if it benefits us to maintain it. (political version)
5. Because biodiversity is the origin of beauty in the world and to study it is to cultivate the heart.
*6* Biodiversity is key when an ecosystem experiences a disturbance. This can be a fire, flood, disease epidemic etc. A more diverse community that have different adaptive strategies will be more likely to survive and rebound.
What is the process which trees remove water from soil and release it through the leaves?
This process is called transpiration. Trees take up water from the soil through their roots and release it through small pores on their leaves called stomata. As the water evaporates from the leaves, it creates a pull that draws more water up from the roots to maintain the flow of nutrients throughout the tree.
How does biodiversity stabilize ecosystem?
Decreases in biodiversity result in a loss of genetic variation. This affects the ecosystem in varying levels of severity. For example, if you lose a pack of wolves in the forest, in that group you lose a genetic line that can hunt well by scent, then the prey species of those wolves (such as rabbits) may increase, they will eat more vegetation, and drive out less successful herbivores from the forest.
What are Causes of biodiversity loss in Kenya?
Basically natural soil erosion occurs from heavy rains, In the Philippines however forests have been cleared to make way for agriculture. The problem is that these forest were originally located on slopes and the trees provided resistance for the rain, now the slope provide a channel for rain and trees are no longer there to resist the rain
There are few main reasons why genetic variations occues, Theres one called Chromosomal abberation, this usually occurs during crossing over in the stage prophase I during meiosis (form of sexual reproduction) What occurs is a duplication, deletion, or a rearrangement of chromosomal segments. So a chromosome might take in information, but it won't exchange and with the other chromosome. The next is Gene mutation, and this results in a change in the stored genetic info meaning one nucleotide is changed. ex GAG TCC TGT can be switch into GAG TTC TGT, because that middle nucleotide was altered this resulted in a new code for a different amino acid, so there fore a new protein was created, resulting in a mutated gene. There are a few others but these are two reasons. Others would be Gene Segregation, Fertlization, Non-disjunction - David
