Question 4:

What is the primary diet of oligochaetes?

Click to see Hint ⬇
Consider the ecological role of oligochaetes in nutrient cycling.
Click to see Answer ⬇
Detritivorous diet - Oligochaetes play a crucial role in ecosystems by breaking down and recycling organic material through their detritivorous diet.

Question 5:

Which insect is known for its role in the process of decomposition?

Click to see Hint ⬇
This insect is often associated with dung.
Click to see Answer ⬇
Dung beetle - Dung beetles help break down dung, which aids in nutrient recycling and soil health.

Question 6:

What is the primary source of energy for most ecosystems?

Click to see Hint ⬇
Think about the process that allows plants to produce food.
Click to see Answer ⬇
Sunlight - Sunlight is essential for photosynthesis, the process by which plants convert light energy into chemical energy, providing the basis for most food chains in ecosystems.

Question 7:

Which of the following is an example of a decomposer in an ecosystem?

Click to see Hint ⬇
Think about organisms that break down dead organic matter.
Click to see Answer ⬇
Mushroom - Mushrooms and other fungi play a vital role in breaking down dead organic matter, returning nutrients to the soil.

Question 8:

What is the term for the relationship between two species in which one benefits and the other is neither helped nor harmed?

Click to see Hint ⬇
This type of relationship involves one species benefiting without impacting the other.
Click to see Answer ⬇
Commensalism - In commensalism, one species benefits while the other is neither helped nor harmed, illustrating a neutral interaction.

Question 9:

Which biome is characterized by low temperatures, little precipitation, and permafrost?

Click to see Hint ⬇
This biome is associated with extreme cold and frozen ground.
Click to see Answer ⬇
Tundra - The tundra is a cold, treeless biome with permanently frozen subsoil, making it a unique and harsh environment.

Question 10:

What is the process by which green plants use sunlight to synthesize food from carbon dioxide and water?

Click to see Hint ⬇
This process involves the use of sunlight to create food for plants.
Click to see Answer ⬇
Photosynthesis - Photosynthesis is the fundamental process by which plants convert light energy into chemical energy, producing their own food.

Question 11:

What is the term for the process by which water evaporates from the leaves of plants?

Click to see Hint ⬇
This process involves water loss from plant leaves.
Click to see Answer ⬇
Transpiration - Transpiration is a crucial process in the water cycle, where water is absorbed by the roots of plants and released as vapor through the leaves.

Question 12:

Which of the following best describes a keystone species in an ecosystem?

Click to see Hint ⬇
This species has a disproportionately large impact on its ecosystem.
Click to see Answer ⬇
A species that has a significant impact on the structure of an ecosystem - Keystone species play a critical role in maintaining the structure and function of an ecosystem, often disproportionately to their abundance.

Question 13:

What is the primary factor contributing to the formation of deserts?

Click to see Hint ⬇
Deserts are known for their dry conditions and scarcity of water.
Click to see Answer ⬇
Lack of water - Deserts are characterized by low precipitation levels, resulting in an arid environment with limited water availability.

Question 14:

Which of the following is an example of a biotic factor in an ecosystem?

Click to see Hint ⬇
Biotic factors encompass living organisms within an ecosystem.
Click to see Answer ⬇
Grass - Biotic factors are living components of an ecosystem, including plants, animals, fungi, and microorganisms.

Question 15:

What is the term for the process of gradual change in an ecosystem over time?

Click to see Hint ⬇
This process involves the gradual development of an ecosystem over time.
Click to see Answer ⬇
Succession - Succession involves the sequential establishment of different species in an area, leading to changes in the ecosystem's structure and composition.

Question 16:

What is the primary cause of eutrophication in aquatic ecosystems?

Click to see Hint ⬇
The overabundance of a certain substance is the main culprit.
Click to see Answer ⬇
Excessive nutrients from fertilizers - Eutrophication is primarily caused by an overabundance of nutrients, often from agricultural runoff, which leads to excessive plant and algal growth, depleting oxygen levels in the water and harming aquatic life.

Question 17:

What is the term for the process by which a species gradually adapts to its environment over time?

Click to see Hint ⬇
This process involves the survival of the fittest.
Click to see Answer ⬇
Natural selection - Natural selection is the mechanism by which species gradually adapt to their environment over generations, as individuals with advantageous traits are more likely to survive and reproduce, passing on those traits to their offspring.

Question 18:

Which of the following is an example of a top-down control on an ecosystem?

Click to see Hint ⬇
This type of control starts from the top of the food chain.
Click to see Answer ⬇
Predator removal leading to an increase in prey population - Top-down control occurs when the abundance or behavior of top predators influences the population dynamics or behavior of their prey, leading to cascading effects throughout the ecosystem.

Question 19:

What is the term for the relationship between two species in which one benefits while the other is harmed?

Click to see Hint ⬇
One organism benefits while the other is harmed.
Click to see Answer ⬇
Parasitism - Parasitism is a type of symbiotic relationship in which one organism, the parasite, benefits at the expense of the host organism, often causing harm or reduced fitness.

Question 20:

Which of the following is a characteristic of K-selected species?

Click to see Hint ⬇
These species focus on quality over quantity when it comes to offspring.
Click to see Answer ⬇
Few offspring with parental care - K-selected species are characterized by investing heavily in a small number of offspring, providing parental care and ensuring their survival to reproductive age.
