Answer:
Sunlight is the main role. Sunlight passes through the leaves and then goes through the rest of the plant.
Explanation:
PHOTOSYNTHESIS
6CO2 + 6H2O + light energy = C6H12O6 + 6O2
The correct answers are;
A.) High energy sugars
A) ATP
The light-independent (dark) reactions are chemical reactions of photosynthesis which occurs within the stoma in plant chloroplast. These reactions use the products of light-dependent reactions which are ATP and NADPH with some enzymes (such as RuBisCO) to carry out its processes. Carbon dioxide and other compounds are converted to produce high energy sugars (glucose) which is used by the plant.
Glycolysis is the cellular degradation of the simple sugar (glucose) to produce pyruvic acid (also known as pyruvate), and ATP (adenosine triphosphate) is used as an energy source.
Answer:
Glossopteris and Lystrosaurus
Explanation:
Glossopteris is an ancient plant flora and Lystrosaurus is a fossil fauna, and both are found in many of the landmasses on earth. The Glossopteris flora appeared about 300 to 200 million years back and the Lystrosaurus appeared about 250 million years back on earth. They both existed from the time of late Permian to early Triassic age.
Both these fossils played an important role in understanding the continental drift theory or the plate tectonic theory. This evidence enabled geologists to understand how the continents have moved across the large ocean basin from one place to another and at what rate they are drifting currently. It helped in understanding how the super-continent Pangaea had broken into Laurasia and Gondwanaland, and further broken into the present location of the plates.
Answer:
B.ocean trench
Explanation: When tectonic plates slide against each other one overlaps the other.
Answer:
There are several environmental factors that causes changes in the ecosystem and the population of that area such as invasive species, extreme weather, land use change, pollution and disease.
Lets take invasive species as environmental factor. Introduction of invasive species can cause a huge change in the ecosystem and affects the native population in that area. it increases the competition for food resources and decreases the survival rate of their preys.
For example: Water hyacinth (Eichhornia crassipes). It is an invasive plant species that has very bad impact of native population as well as other population, like it reduces biological diversity, oxygen loss, decreased phytoplankton productivity, eliminate plants that animals use for nesting, and alter animal communities by blocking access to the water.
Thus invasive population can affect population by reducing biodiversity, water shortages, decreasing availability and quality of key natural resources, disturb the food chain and can cause natural calamities.
Invasive species affect the resources that native species are using and that decreases the carrying capacity of the native population as it disturbs the whole food chain.
