Answer:

Animals get their energy by eating food.
Some animals eat plants. These are called herbivores.
They can also be known as primary consumers.
Carp is a herbivorous fish.
Nutrition – being able to get energy out of food ... Plants get their energy from the sun. ... Some animals eat both plants ... Predators. Predators eat other animals. Sharks eat fish so they are.
He wondered, Does the position of the pot determine the growth of the stem?<span>
He hypothesized that the plant’s stem grows perpendicular to the soil.
</span><span>To test his hypothesis, Brian placed the pot horizontally. He checked the plant after two weeks.
</span>
<span>Brian observed that a plant’s stem grows against gravity.
</span><span>On analysis, Brian found that the plant grew parallel to the soil. He modified the hypothesis, and then retested the experiment.
</span><span>Brian communicated the results to his science class.</span>
<h3><u>
The following events are identified as chemical weathering:</u></h3>
- The minerals in a marble statue react with water to form acids and pores in the structure.
- The rocks in a region are streaked orange after being exposed to repeated rains.
<em><u>Reason: </u></em>
When the weathering process occurs due to <em>chemical reaction</em>, then it is considered as chemical weathering.
In <em>the first case</em>, minerals of marble statue are <em>reacting</em> with water to cause weathering. In the <em>second case</em>, due to the <em>acidificaion reaction</em>, the change of the color has happened after exposure to the repeated rains.
<h3><u>
The following events are identified as Mechanical weathering:</u></h3>
- A piece of rock crumbles after being constantly thrashed by strong waves.
- Industrial runoff forms cracks in a rocky structure in its path.
<em><u>Reason:</u></em>
When the rock is broken into simple pieces <em>without any chemical reaction </em>it is considered as mechanical weathering.
In the <em>first cause</em>, due to the <em>abrasion</em> caused by the strong waves, weathering has happened, in the <em>second case</em> industrial run off may be of varying temperature and thus may cause <em>heating or cooling</em> of the rock and causes weathering.
