The main type of evidence the scientists used is fossils.
Palaeontologists study plants and animals that existed in the geologic past. To do so, they use fossils and try to determine an organism's evolution and relationship with the environment and other organisms. In this example, palaeontologists used fossils from ancient horses that have gone extinct and try to decipher their evolutionary path. Recognising the evolutionary steps of the ancient horses will make it possible to compare them to the modern horses.

Scientists decipher the structure of the primitive living system that once existed on Earth with the help of fossil records.

Further Explanation:

<u>Evolution is the phenomenon that occurs continuously on this Earth</u>. Due to the natural selection process, the organism that better fits into the environment and prevails in a particular environment gets selected because factors like their physiological and biochemical process allow them to survive in that particular environment condition.

<u>The evolution can be studied using the phylogenetic tree build by collecting evidence from fossil fuel.</u> Studying biochemistry and genetic data from these records allows the scientist to decipher the lineages and draw the phylogenetic tree from these data. <u>The monophyletic phylogenetic tree can even reveal about the ancestor of modern-day living organism. </u>

Gemiola [76]

Answer:

dependent variable

Explanation:

In an experiment, a line graph can be used to display the results of the experiment. A line graph, which posseses two axis namely: x-axis or horizontal axis and y-axis or vertical axis, can be used to show the relationship between the independent and dependent variables in an experiment.

The independent variable, which is the variable subject to change is displayed on the X-axis while the dependent variable is displayed on the vertical or Y-axis.

Outline three examples of cycles of inorganic nutrients. For each, outline the uses of the nutrients in living organisms, its me
Serggg [28]

The three examples of cycles of inorganic nutrients are Nitrogen, carbon and sulphur cycle.

Nitrogen is required to make amino acids and DNA in organisms. Carbon is the main component of glucose through which organism make energy, about 18 per-cent of the human body comprises carbon. Sulphur is an important constituent of some proteins, amino acids and enzyme cofactors.

Explanation:

The biogeochemical cycles like the nitrogen cycle are responsible for converting nitrogen into many chemical forms as nitrates, nitrites, ammonia. This process involves degrade decomposing animal and plant matter and naturally cleaning the environment also nitrites and nitrates become biofertilizers. The plants take nitrogen through their roots and in turn primary consumer in food chain ie. organisms consume the plant and eventually releases nitrogen as a waste material, dead and decaying body to the soil and cycle goes on.

In the carbon cycle the carbon is exchanged from the atmosphere to the organisms and then again to the environment. Plants perform photosynthesis by using carbon dioxide, primary consumer eats it and gets nutrition to perform cellular respiration, in turn, gets energy which gets dissipated and stored as biomass eventually in the course consumer die and replenish the soil with carbon. The Carbon emitted will keep cycling through air, water and soil.

The sulphur cycle involves the movement of sulphur between rocks, water and living beings and plants. Plants ( producers) absorb sulphur dissolved in water and animal consume these plants to replenish their sulphur requirement. And when organism die, sulphur enter the cycle again.

There will be a transfer of these inorganic nutrients to the trophic level in food chain.

Which of the following is an abiotic factor in the ecosystem?
Naily [24]

---- *Well, since there is really no specific ecosystem that was asked about in the question, I will just list some common and basic abiotic factors found throughout most ecosystems (maybe you can match this with the ecosystem you are talking about).

---------------------------------------------------------------------------------------------------------

Abiotic factors: nonliving parts of an ecosystem

Some abiotic factors include: ROCKS, SOIL, AIR, SUN, WATER, ETC.
