In a tropical rain forest, tall trees crowd together, blocking the path of sunlight to the wet forest floor. Among the plants adapted to these conditions are climbers, such as vines that grow up along the tree trunks. Other plants, such as orchids, grow attached to tree branches and are not rooted in the ground. Even a small area of forest provides various habitats for vast numbers of animal and plant species. Many insects and birds are plant pollinators. Fruit-eating animals, such as birds and bats, spread seeds. Insects, fungi, and bacteria break down plant and animal matter, releasing nutrients into the soil. Predators, such as jaguars and snakes, feed on smaller animals.

Answer:
A living thing like a cheetah relies on a flat land biome because a biotic living thing like a cheetah relies on an abiotic factor like sunlight and vision.
Explanation: Because how would they hunt.
Biotic and abiotic factors both are dependent on each other.
What is biotic and abiotic factors?Biotic factors are living things within an ecosystem; such as plants, animals, and bacteria, while abiotic are non-living components; such as water, soil and atmosphere.
Abiotic factors in a tropical rain forest include water, a warm climate, sunlight, and soil nutrients. All organisms and populations in the tropical rain forest depend on water and warm temperatures. Plants depend directly on sunlight and soil nutrients.
Biotic factors in a tropical rain forest include all of the organisms that live there. Vines and orchids depend on the trees as a way to reach the light.
Some plants depend on insects or birds for pollination, or birds or bats to spread their seeds. Indirectly the plants depend on organisms that release nutrients into the soil.

What is mineral ?A mineral or mineral species is, generally speaking, a solid chemical compound that naturally occurs in pure form and has a very well-defined chemical composition as well as a particular crystal structure.
Each crystal structure that makes up a chemical compound that exists naturally as a separate mineral species. As an illustration, silicon dioxide is a component of the same mineral species as quartz and stishovite.
They can be mined and have the potential to be exploited as a source of metal. Manganese, iron ore, and bauxite are examples of metallic minerals, which can be either ferrous or non-ferrous. While ferrous minerals do contain iron, non-ferrous minerals do not.
Thus, option B is correct.

Explanation:
On a hot summer day, air rises most quickly when it is above a
forest
lake
desert
river
On a hot summer day, air rises most quickly when it is above a desert. The correct option is C.
What is a desert?A desert is a barren area of land with little precipitation and, as a result, hostile living conditions for plant and animal life.
The lack of vegetation exposes the ground's unprotected surface to denudation. Arid or semi-arid regions cover roughly one-third of the Earth's land surface.
Although the majority of deserts, such as the Sahara in North Africa and the deserts of the southwestern United States, Mexico, and Australia, occur at low latitudes.
Arid climates have less cloud cover than humid climates, and cloud tops reflect a significant amount of the sun's energy back into space, reducing surface heating. On a hot summer day, air rises the fastest above a desert.
Thus, the correct option is C.

Which situation is an example of heat transfer by radiation?
Answer:
This type of transfer takes place in a forced-air furnace and in weather systems, for example. Heat transfer by radiation occurs when microwaves, infrared radiation, visible light, or another form of electromagnetic radiation is emitted or absorbed. An obvious example is the warming of the Earth by the Sun.
Answer:
the heat from the hotter to the colder region. Some common examples of Radiation are Ultraviolet light from the sun, heat from a stove burner, visible light from a candle, x-rays from an x-ray machine. All life on Earth depends on the transfer of energy from the Sun, and this energy is transferred to the Earth over empty space.
