b. The undergrowth of rainforests is choked by weeds and plants.
c. Rainforests are characterized by high levels of rainfall.
d. Not all rainforests are tropical rainforests.
Rainforests are responsible for most global oxygen turnover is not true concerning the rainforests.
Further Explanation:
Rainforests are dense jungle and considerably tall. They are referred to as rainforest because every year, high rainfall occurs in these areas. The climate in these forests is very humid and hot, so the plant and animal exist in these areas and are adapted to this environment. The normal temperature of these areas is 70 degree Celcius – 85 degree Celcius-. Many household items are obtained from these forests. Most of South Africa and western Africa has the largest rainforest. In India and Australia, smaller rainforests are present.
Rainforest provides numerous benefits such as maintain the climate, greenhouse effect and provide space for animals and plants. Also, they produce food and medicine for many organisms. They are not responsible for providing global oxygen because plant present in humid areas takes a higher amount of oxygen to fee vegetation.

Rainforests have a unique ecological structure where the dense canopy of trees filters out much of the sunlight, leading to limited light penetration on the forest floor. The correct answer is b. The undergrowth of rainforests is choked by weeds and plants.
As a result, the undergrowth of rainforests typically has limited vegetation due to the lack of sufficient light, rather than being choked by weeds and plants. The majority of plant life and diversity in rainforests is concentrated in the upper layers of the forest, such as the canopy and understory.
Rainforests are characterized by a dense canopy formed by tall trees that grow close together and have large, spreading branches. These trees create a thick layer of foliage that blocks much of the sunlight from reaching the forest floor. Consequently, the amount of available light in the understory, the lower layer of the forest, is significantly reduced.
Therefore, the correct answer is b. The undergrowth of rainforests is choked by weeds and plants.

Answer:
The correct answer is - humpback whales →sea turtles→humans→dolphins.
Explanation:
The hearing of sound is measured in hertz which is the unit of the sound that depends on the different frequencies of individual produce. The range of hearing sound is different in different animals.
Humpback whales produce sound between 30 to 8000 Hz however whales sense the vibration made by their song or sound by another whale. Sea turtles are able to hear in between the 20 to 1000 Hz whereas humans are able to hear 20 to 20000 Hz.
The highest hearing range of the sound is by dolphins from giving options as they are able to hear sound between 40 to 130000.
Thus, the correct answer is- humpback whales →sea turtles→humans→dolphins.
