Answer:
Explanation:
First, let's identify the tools needed.
Since the biology class is studying the temperature, they will likely need a <u>thermometer</u>. Also, they are gathering information about the growth of the plants. This could use a <u>balance </u>of a meterstick.
Next, recall the difference between quantitative and qualitative data.
- <u>Quantitative</u>: Measurable and numerical results found using scientific instruments/devices
- <u>Qualitative</u>: Data found using the senses, such as descriptions and diagrams.
Since the class is measuring temperature and growth using tools, it must be quantitative data.
We can eliminate choices A and B, because they claim the class will gather qualitative data. Then, we can eliminate choice D, because a beaker and timer won't help with temperature and growth. That leaves choice C as the correct answer.
Answer:
Option (1) and (3)
Explanation:
The ocean covers a large portion of earth and the temperature of the ocean rises due to the high absorption of heat. This is because of the higher amount of incoming solar radiation and the increasing green house gases in the atmosphere of the earth.
This increasing temperature of the ocean has certain negative effects.
Due to the increasing ocean temperature, the ocean water will become warm that will enhance the temperature of the polar water, as a result of which the glaciers and ice caps of the polar region will melt.
The increasing ocean water temperature will lead to the evaporation of water into the atmosphere, which will eventually cause rainfall. This will cause flooding in the low-elevated coastal areas. There occurs increasing frequency of major storms.
Thus, the correct answers are options (1) and (3).
The major difference between the flow of matter and of energy is that the flow of matter occurs in a cyclic manner i.e. it is recycled, however, the flow of energy in an ecosystem is unidirectional which means, it is not recycled. The flow of matter follows the following path
1) Decomposers release nutrients when they break down dead organisms
2) The nutrients are taken up by plants through their roots
3) The nutrients pass to primary consumers when they eat the plants
4) The nutrients pass to higher-level consumers when they eat lower-level consumers
5) When living things die, the cycle repeats
In case of flow of energy, the energy flows through an ecosystem in one direction, from photosynthetic organisms to herbivores to omnivores and carnivores and decomposers, less and less energy becomes available to support life. This loss of usable energy occurs because each energy transfer results in the dissipation of some energy into the environment as heat
