Explanation:

They became extinct, so they did not exist when the younger rock layers formed. Option D.

The most likely scenario based on the information provided is that the organisms that became fossilized in older rock layers became extinct, and therefore, they did not exist when the younger rock layers formed.

Fossils are the preserved remains or traces of organisms from the past, and they provide valuable insights into the history of life on Earth. The distribution of fossils in rock layers follows the principle of superposition, which states that younger rock layers are deposited on top of older ones.

This implies that the fossils found in older rock layers represent organisms that lived in the past and were preserved through the fossilization process.

If the older rock layers contain fossils of many kinds of organisms that are not found in younger rock layers, it suggests that those organisms no longer existed by the time the younger rock layers formed. The absence of their fossils in younger layers indicates that either the organisms became extinct or their populations shifted to different habitats or regions where their remains were not preserved as fossils.

This phenomenon aligns with the concept of extinction, which is the complete disappearance of a species or a group of organisms. Extinction can occur due to various factors such as environmental changes, competition, predation, or other selective pressures.

Organisms that became extinct would not be present in subsequent rock layers because they were no longer alive or did not have a viable population to leave behind fossil remains.

Therefore, the most reasonable explanation is that the organisms that became fossilized in older rock layers became extinct, and this is why they are not found in younger rock layers. SO Option D is correct.

'Humans' contributes the most to global climate change according to the Intergovernmental Panel on Climate Change.

What do you mean by climate?

Climate is the average weather conditions in an area over a long period of time, usually 30 years or more. It includes patterns of temperature, precipitation, humidity, wind and other variables. It is important in determining where and how people live, what plants and animals can survive and how vulnerable species are to changes in the environment.

Humans are the leading cause of global climate change because of the amount of greenhouse gases that are released into the atmosphere as a result of human activity. This includes burning fossil fuels for energy, which produces carbon dioxide, and deforestation, which reduces the amount of carbon dioxide absorbed by plants. Additionally, other human activities, such as animal agriculture, result in the release of methane, another powerful greenhouse gas. As a result of these activities, the concentration of greenhouse gases in the atmosphere has been steadily increasing, leading to a rise in global temperatures.

Hence, Option C is correct.

Through the process of natural selection, sea urchins have developed spines that serve as a defense mechanism against predators and a means of anchoring themselves in turbulent waters. This adaptation allows them to better survive in their environment, with individuals possessing longer or stronger spines being more likely to pass on their genes to the next generation. As a result, the population of sea urchins gradually becomes better adapted to their surroundings, demonstrating the power of natural selection in shaping the evolution of species.

The energy pyramid demonstrate a great amount of energy is lost traveling up the energy pyramid.

The energy pyramid demonstrates that as you move up from the producers (bottom level), which convert sunlight into energy through photosynthesis, to the primary consumers (herbivores), to the secondary consumers (carnivores that eat herbivores), and finally to the tertiary consumers (carnivores that eat other carnivores), there is a decrease in available energy.

This is because energy is lost at each level through processes such as respiration, heat loss, and waste. Therefore, the top predators of an ecosystem have access to the least amount of energy.
