Shedding leaves in dry season helps in what way?

Reduction of transpiration rate
Helps to retain minerals
Allows growth of new cells
Helps to form new layers and leaves

Correct Answer

A. Reduction of transpiration rate

Explanation

Shedding leaves in the dry season helps in reducing the transpiration rate. Transpiration is the process by which plants lose water through their leaves. During the dry season, water availability is limited, so plants shed their leaves to minimize water loss and conserve moisture. By reducing transpiration, plants can better survive in dry conditions and maintain their water balance.

Ferns, cacti, and moss are examples of what?

Epiphytes
Lithophyte
Epibiont
Myxomycetes

Correct Answer

A. Epiphytes

Explanation

Ferns, cacti, and moss are examples of epiphytes. Epiphytes are plants that grow on the surface of other plants, typically trees, without harming or taking nutrients from the host plant. They obtain moisture and nutrients from the air, rain, and debris that accumulates around them. Ferns, cacti, and moss are all adapted to live in this way, attaching themselves to the host plant and using it as support while obtaining the resources they need to survive.

Which is the biggest influence on vegetation type found in a green region according to Koppen?

Temperature
Climate type
Soil profile
Water

Correct Answer

A. Climate type

Explanation

Koppen's classification system categorizes vegetation types based on climate types. Climate type determines the overall weather conditions, including temperature, precipitation, and humidity, which greatly influence the types of plants that can thrive in a particular region. Temperature, soil profile, and water availability are all important factors, but they are ultimately influenced by the climate type. Therefore, the biggest influence on vegetation type found in a green region, according to Koppen, is climate type.

Which refers to the development of an ecosystem in an area that has never had a community living within it?

Pioneering plants
Primary succession
Coriolis effect
Phytochemicals

Correct Answer

A. Primary succession

Explanation

Primary succession refers to the development of an ecosystem in an area that has never had a community living within it. This process occurs in areas that have been completely devoid of life, such as newly formed volcanic islands or areas that have been completely wiped clean by a natural disaster. Pioneering plants are the first organisms to colonize these areas, gradually paving the way for the establishment of a more complex and diverse community. The Coriolis effect is a phenomenon related to the rotation of the Earth and has no direct relation to the development of an ecosystem. Phytochemicals are chemical compounds produced by plants for various purposes and are not directly related to the development of an ecosystem.

Which of the following is the lowest Strata Layer?

Herb Layer
Canopy Layer
Understory Layer
Immature Layer

Correct Answer

A. Herb Layer

Explanation

The herb layer is the lowest strata layer in a forest. It consists of low-growing plants, such as grasses, herbs, and ferns, that grow close to the ground. These plants receive less sunlight due to the shading from the layers above, and they play an important role in the ecosystem by providing ground cover, preventing soil erosion, and providing habitat for small animals and insects. The canopy layer is the highest layer, consisting of the tops of the tallest trees, while the understory layer is below the canopy and consists of shorter trees and shrubs. The immature layer refers to young trees that have not yet reached the canopy.

Which of the following grows in Tropical Rainforests and requires a continuous amount of high temperatures with an abundant amount of precipitation?

Megatherms
Epiphytes
Lithophyte
Lythophyte

Correct Answer

A. Megatherms

Explanation

Megatherms are the correct answer because they are organisms that thrive in tropical rainforests, where they require a continuous supply of high temperatures and abundant precipitation. Megatherms include large plants and animals that are adapted to the warm and humid conditions of the rainforest, such as tropical trees and certain species of insects and reptiles. They are able to withstand and utilize the constant heat and moisture of the rainforest environment to survive and thrive.

8.

Which of the following is directly below the Emergent Layer?

Canopy Layer
Immature Layer
Forest floor
Understory Layer

Correct Answer

A. Canopy Layer

Explanation

The Canopy Layer is directly below the Emergent Layer in a forest. The Emergent Layer is the highest layer of the forest, consisting of the tallest trees that receive the most sunlight. Below the Emergent Layer is the Canopy Layer, which is made up of the branches and leaves of smaller trees that form a dense covering. This layer provides shade and shelter to the layers below, including the Understory Layer and the Forest Floor. The Immature Layer is not a recognized layer in the forest ecosystem.

Trees protect themselves with which of the following to ward off herbivory?

Thorns
Thick skins
Phytochemicals
Bark

Correct Answer

A. Phytochemicals

Explanation

Phytochemicals are natural compounds produced by plants that serve as a defense mechanism against herbivory. These chemicals can be toxic or unpalatable to herbivores, deterring them from feeding on the plant. By producing phytochemicals, trees are able to protect themselves and reduce the risk of being consumed by herbivores. This defense mechanism allows trees to survive and thrive in their environment.

Which of the following is where the Southeast and Northeast Trade Winds converge near the Equator?

Doldrums
Convergence zone
Intertropical zone
Confluence

Correct Answer

A. Doldrums

Explanation

The correct answer is Doldrums. The doldrums are a region near the equator where the Southeast and Northeast Trade Winds converge. In this area, the winds are light and variable, resulting in calm and windless conditions. This convergence of trade winds creates a low-pressure zone, which is characterized by hot and humid weather. The doldrums are known for their lack of consistent winds, making it difficult for sailing ships to navigate through this region.
