Organisms that are characterized by being unicellular, photosynthetic, and having double shells made of silica are known as B. diatoms.
<h3>Photosynthetic</h3>
By converting light energy into chemical energy through a process called photosynthesis, plants and other living things can subsequently release that chemical energy to power their activities. The name "photosynthesis" comes from the Greek words "phs" for "light" and "synthesis" for "putting together." Some of this chemical energy is stored in carbohydrate molecules like sugar and starch, which are created from carbon dioxide and water. These creatures are referred to as photoautotrophs and include the majority of plants, algae, and cyanobacteria. Most of the energy required for life on Earth is produced and maintained through photosynthesis, which also produces and maintains the oxygen concentration of the atmosphere.

B
The European weather model sometimes differ from predictions made by the American weather model because <u>The two models use different types of data measurements</u>
<u></u>
<u>The amount of solar energy that reaches Earth</u> is changed by the Milankovitch cycles
Explanation:
(I)
Remember that in the United States, they use different SI units as compared to Europe. For example, Europe uses degrees Celsius as a measure of temperature while the United States uses Fahrenheit. In addition, the United uses Pounds for weight measurements while Europe uses Kilograms and grams. The US uses miles while Europe uses kilometers. The United States uses yards while Europe uses meters.
The differences can cause a difference in the input and output measurement gotten from the models. However, the models are the same because the basic principles of weather across the world are the same.
(II)
Milankovitch cycles are differential changes in the earth as it revolves, around the sun, in its orbit. They explain the changes in the orbital eccentricity of the earth's orbit, the changes in the tilt of the earth (obliquity), axial and apsidal precessions. All these affect how the earth is oriented, in space, towards the sun. The orientation affect how the sun rays ‘hit’ the earth. Differences in how different places on earth receive the sunlight affect the climate of the regions. These changes occur very slowly, relative to our time, hence the changes also are hard to perceive except over decades and millennia.

Answer: The process of the scientific method involves making conjectures (hypotheses), deriving predictions from them as logical consequences, and then carrying out experiments or empirical observations based on those predictions. ... Scientists then test hypotheses by conducting experiments or studies.
The pyramid of numbers only compares the number of organisms present in each trophic level at A PARTICULAR TIME. This pyramid can be inverted if organisms of one trophic lvl is parasitic on organisms of another trophic lvl. or when threre are many small organisms feeding of one trophic level feeding on a large organism of anoyher trophic lvl.
For eg. tree→aphid →protozoa, the pyramid of numbers is upside down
however pyramid of energy is always in a pyramid shaped as it compares the total energy in each trophic level OVER A PERIOD OF TIME. more energy is lost when we mive along a food chain hence the shape is ALWAYS pyramid.
