1.
What Forest has annual dry seasons?
Correct Answer
C. Tropical Seasonal Forest
Explanation
Tropical Seasonal Forests experience annual dry seasons. These forests are found in regions with distinct wet and dry seasons, where precipitation is concentrated during the wet season and significantly reduced during the dry season. This type of forest is characterized by a diverse range of plant and animal species that have adapted to the alternating wet and dry conditions.
2.
What Biome can freeze in any month?
Correct Answer
B. Tundra
Explanation
The correct answer is Tundra. The Tundra biome can freeze in any month due to its extremely cold temperatures. It is characterized by long, harsh winters and short, cool summers. The freezing temperatures in the Tundra biome make it difficult for plants and animals to survive, resulting in a unique and fragile ecosystem.
3.
What are bays where rivers empty to the sea, mixing freshwater with saltwater?
Correct Answer
D. Estuaries
Explanation
Estuaries are bays where rivers empty into the sea, creating a unique environment where freshwater from the river mixes with saltwater from the sea. This mixing of waters results in a brackish water habitat that is home to a diverse range of plant and animal species. Estuaries are important ecosystems that provide valuable nursery grounds for many marine species and also serve as a buffer zone, protecting coastal areas from erosion and storm damage.
4.
What are wetlands with trees?
Correct Answer
A. Swamps
Explanation
Swamps are wetlands with trees. They are characterized by the presence of waterlogged soils and are typically dominated by trees and shrubs. Swamps are found in low-lying areas where water accumulates, creating a habitat that supports the growth of trees. Unlike marshes, which are dominated by grasses and reeds, swamps have a higher density of woody vegetation. Bogs and fens, on the other hand, are also wetlands but are characterized by the presence of peat and different types of vegetation.
5.
What is the reduction of habitat into small isolated patches?
Correct Answer
C. Fragmentation
Explanation
Fragmentation refers to the process of breaking up a habitat into smaller, isolated patches. This can occur due to various human activities such as urbanization, deforestation, or the construction of roads and infrastructure. Fragmentation can have negative effects on biodiversity as it disrupts the connectivity between different habitats, making it difficult for species to move and disperse. It can lead to the loss of certain species, reduced genetic diversity, and increased vulnerability to environmental changes. Therefore, fragmentation is the correct answer to the question.
6.
What is Biodiversity?
Correct Answer
A. The Variety of Living Things.
Explanation
Biodiversity refers to the variety of living organisms present in a particular ecosystem or on the entire planet. It encompasses all forms of life, including plants, animals, microorganisms, and their interactions with each other and their environment. This term is used to describe the richness and abundance of different species and genetic diversity within a given habitat. Biodiversity is essential for the stability and functioning of ecosystems, as it provides numerous ecosystem services such as pollination, nutrient cycling, and climate regulation.
7.
What is a Phylogenetic species concept?
Correct Answer
B. It identifies Genetic similarity.
Explanation
The correct answer is "It identifies Genetic similarity." The phylogenetic species concept defines species based on their evolutionary history and common ancestors. It focuses on genetic similarity among individuals to determine whether they belong to the same species or not. This concept considers the genetic relationships and evolutionary connections between organisms to classify them into distinct species.
8.
What is a cool rain forest often enshrouded in fog?
Correct Answer
C. Temperate Rainforest
Explanation
A cool rainforest often enshrouded in fog is known as a temperate rainforest. This type of rainforest is characterized by moderate temperatures and high levels of rainfall throughout the year. The fog in these forests is created by the cool ocean currents that flow along the coastlines, creating a unique and misty environment. The temperate rainforest is home to a variety of plant and animal species, including mosses, ferns, and large evergreen trees. These forests are found in regions with mild, wet climates, such as the Pacific Northwest of North America and parts of Chile and New Zealand.
9.
An area where precipitation takes place rarely?
Correct Answer
B. Dessert
Explanation
A desert is an area where precipitation takes place rarely. Deserts are characterized by extremely low rainfall, often less than 250 millimeters per year. They are typically hot and dry, with sparse vegetation and little to no surface water. The lack of precipitation in deserts is due to factors such as high pressure systems, geographic location, and the presence of mountains that block moisture. As a result, deserts have arid and inhospitable conditions, making them an area where precipitation is scarce.
10.
What is Vertical zonation?
Correct Answer
D. Vegetation zones defined by altitude.
Explanation
Vertical zonation refers to the division of vegetation into distinct zones based on changes in altitude. As altitude increases, the climate and environmental conditions change, leading to variations in the types of plants that can survive and thrive. Different vegetation zones can be observed at different altitudes, with specific plant communities adapted to the conditions of each zone. This concept helps in understanding the distribution of vegetation and studying the ecological patterns that exist at different elevations.
