Geological timeline is the chronological dating of the organisms and the geological happening in the orderly manner of the years and dates. The oldest mammals lived 200 million years ago.
<h3>What are the different species that arrived in the geological timelines?</h3>
5 million years ago humans arrived, 200 million years ago first mammal organism, 1.5 billion years ago complex single-celled organisms and 4.5 billion years ago Earth was formed.
The geological timeline is important as it portrays the presence and arrival of the organisms and the formation of some of the structures.
Therefore, mammals arrived at option B. 200 million years ago.

Answer:
light
Explanation:
An abiotic factor is a non-living component in the environment. This can be either a chemical or physical presence. Abiotic factors fall into three basic categories: climatic, edaphic and social. Climatic factors include humidity, sunlight and factors involving the climate. Edaphic refers to soil conditions, so edaphic abiotic factors include soil and geography of the land. Social factors include how the land is being used and water resources in the area. Five common abiotic factors are atmosphere, chemical elements, sunlight/temperature, wind and water.
Temperature and Light

•••
Temperature of the air and water affect animals, plants and humans in ecosystems. A rise in temperature has the potential to change the way a living thing develops, because it changes the metabolic rate of the organism. All living organisms have a tolerance level for temperature range. For example, a human being would die if he stood out in minus 50 degree temperatures for any length of time. Light exposure often affects the temperature. Areas with direct sunlight are warmer
The mineral form of iron II oxide is known as wüstite. Hematite (69.9% Fe) and Magnetite ( 72.4% Fe) are two other examples of iron oxide. Magnetite has naturally high iron content than Hematite.
iron-to-oxygen ratios of
Hematite
3.79 g of Fe and 1.63 g O
and
Magnetite
22.8 g Fe and 8.70 g O
where Fe symbolise iron and O symbolise oxygen.
He should use a filter and then read it using a machine
The answer is sunlight, chlorophyll, carbon dioxide and water.
In the photosynthesis plants use sunlight as an energy and convert it into chemical energy stored in carbohydrates. Carbon dioxide and water are used for carbohydrate synthesis. This process occurs in the chloroplasts containing chlorophyll, which is necessary for absorbing energy from sunlight.
