24 Midterm Review

Front

What is overfishing?

Back

Overfishing is the practice of catching fish at a rate faster than they can reproduce, leading to a decline in fish populations and long-term damage to marine ecosystems.

Front

What impact does a hurricane have on bird populations?

Back

A hurricane can cause a sharp decline in bird populations due to habitat destruction and loss of food sources.

Front

How do nitrogen-fixing bacteria contribute to the nitrogen cycle?

Back

Nitrogen-fixing bacteria capture nitrogen from the atmosphere and convert it into forms that plants can use, facilitating the nitrogen cycle in ecosystems.

Front

What is the effect of introducing a nonnative species to an ecosystem?

Back

Introducing a nonnative species can disrupt the ecosystem by taking over the habitats of native species, leading to a decline in biodiversity.

Front

What is a temperature inversion?

Back

A temperature inversion is a meteorological phenomenon where a layer of warm air traps cooler air near the ground, affecting weather patterns.

Front

How does a temperature inversion relate to El Nino events?

Back

A temperature inversion can lead to warmer sea surface temperatures in the Pacific Ocean, which is a characteristic of El Nino events.

Front

What is the significance of habitat destruction?

Back

Habitat destruction leads to loss of biodiversity, as species lose their homes and food sources, often resulting in population declines.

Front

What role do ecotourism activities play in marine conservation?

Back

Ecotourism promotes environmental awareness and conservation efforts, helping to protect marine ecosystems rather than harm them.

Front

What is the relationship between competition and population dynamics in ecosystems?

Back

Increased competition for resources can lead to population declines as species struggle to survive and reproduce.

Front

What are the consequences of overhunting on ecosystems?

Back

Overhunting primarily affects land animals but can also disrupt food chains and ecological balance, impacting entire ecosystems.
