How does photosynthesis benefit heterotrophs
- A.
It adds carbon dioxide to the air
- B.
It creates food that they can eat
- C.
It eliminates harmful sugars
Correct Answer
B. It creates food that they can eatExplanation
Photosynthesis is the process by which plants convert sunlight, water, and carbon dioxide into glucose and oxygen. Heterotrophs, such as animals and humans, cannot produce their own food and rely on consuming other organisms for energy. Therefore, photosynthesis benefits heterotrophs by creating food (glucose) that they can consume and obtain energy from. This process forms the basis of the food chain and provides sustenance for all heterotrophic organisms.Rate this question:

Photosythesis and respiration form a cycle that keeps the levels of water and carbon dioxide fairly constant in the atmosphere
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement is false because photosynthesis and respiration do not form a cycle that keeps the levels of water and carbon dioxide fairly constant in the atmosphere. While photosynthesis removes carbon dioxide and releases oxygen, respiration does the opposite by consuming oxygen and releasing carbon dioxide. This creates a balance between the two processes, but it does not keep the levels of water and carbon dioxide constant. Additionally, the water cycle is responsible for regulating water levels in the atmosphere, not photosynthesis and respiration.Rate this question:

Photosynthesis and respiration form a cycle that keeps the levels of _____________ and carbon dioxide fairly constant in the atmosphere
Correct Answer
oxygenExplanation
Photosynthesis is the process by which plants convert carbon dioxide and sunlight into oxygen and glucose, while respiration is the process by which organisms use oxygen to break down glucose and release carbon dioxide. Together, these two processes form a cycle that maintains a balance of oxygen and carbon dioxide in the atmosphere. Through photosynthesis, plants release oxygen into the atmosphere, while respiration by organisms consumes oxygen and releases carbon dioxide. This continuous cycle helps to regulate the levels of oxygen and carbon dioxide, ensuring their relative stability in the atmosphere.Rate this question:

Phototropism means _______________________.
Correct Answer
Growth from sunlight or Light GrowthExplanation
Phototropism refers to the growth or movement of an organism in response to light. It is a natural phenomenon observed in plants, where they tend to grow towards a light source. This is due to the plant hormone called auxin, which accumulates on the shaded side of the plant and causes elongation of cells, resulting in the bending or curvature towards the light. Therefore, the given answer, "Growth from sunlight or Light Growth," accurately describes the concept of phototropism.Rate this question:

Pollination can occur by _________.
- A.
Wind
- B.
Water
- C.
Bees
- D.
Wind, water and bees
Correct Answer
D. Wind, water and beesExplanation
Pollination can occur through various means, including wind, water, and bees. Wind pollination, also known as anemophily, is common in plants that produce lightweight pollen grains that can be carried by air currents. Water pollination, or hydrophily, is seen in aquatic plants where pollen is released into the water and transported to female reproductive structures. Bees and other insects play a crucial role in pollination, known as entomophily, as they transfer pollen from the male parts of flowers to the female parts while foraging for nectar. Therefore, pollination can occur through wind, water, and the assistance of bees.Rate this question:

Sexual reproduction requires two parents.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Sexual reproduction is a process where offspring are produced by the fusion of gametes from two parents. In this type of reproduction, genetic material from both parents combines, leading to genetic diversity in the offspring. This is in contrast to asexual reproduction, where only one parent is involved. Therefore, the statement that sexual reproduction requires two parents is true.Rate this question:
