Answer:

Explanation:

The fossil record shows that different species have evolved over time. The fossil record also provides evidence of how a specific organism evolved from earlier species. The fossil record shows that organisms have become more complex over time. It also shows which organisms lived during the same time period, which have a common ancestor, and which have become extinct.

<h2><u>Answer:</u></h2>

Fossil: is preserved pre historic life form present under ground at high pressure for a long time.Animal die and burried under layers of sediments.

It provides evidence about the history of life on earth. It also shows different groups of organisms, including species,that have changed over time. Because the formation of any fossil depends upon the precise combination of conditions.

As the world changes, plants and animals change with time . From fossils we compare organisms of modern time with ancient , the species we see today are very different from species that lived in the past. Thus, the fossil record can be used to show that organisms changed to meet new condition.

Answer: Water is drawn in through small openings on a sponge's body called OSTIA.

The supportive skeleton of a sponge contains SPICULES which provide protection from predators.

Explanation:

Sponges refer to any of the aquatic animals of the phyllum porifera which is normally characterized with porous structures and has horn-like calcareous internal framework.

Sponges usually have multiple pores called "OSTIA" on their bodies that allow water to enter them.

Most sponges are sessile and because of this, they can't run away from predators. They usually have sharp "SPICULES" which are part of their skeleton that provide them some certain degree of defense. Apart from this, they also produce toxins which poisons predators that attempt to consume them

According to the research, the correct option is photosynthesis. The process of <u>photosynthesis</u> generates the oxygen that we breathe and the food that we eat.

<h3>What is photosynthesis?</h3>

It is the process of obtaining energy from plants, algae and certain bacteria to synthesize organic substances from other inorganic ones.

This metabolic process carried out by some cells of autotrophic organisms is essential for life since, starting from light and inorganic matter, it manages to synthesize organic matter and allows carbon dioxide (CO2) to be fixed from the atmosphere and oxygen to be released.

Therefore, we can conclude that according to the research, the correct option is photosynthesis. The process of <u>photosynthesis</u> generates the oxygen that we breathe and the food that we eat.
