In a predator-prey relationship, the predator benefits (+) while the prey is harmed (-). Which of the following is an example of a predator-prey relationship?
Lion hunting and feeding on a zebra
Which of the following best describes resource partitioning?
Animals of the same species divide up resources to coexist together
Which of the following is an example of mutualism?
Bees pollinating flowers
What is the role of an organism within a particular ecosystem called?
Niche
Which of the following best describes commensalism?
One organism benefits while the other is unaffected
What does a broad niche organism mean?
It has adapted to a wide range of environmental conditions and plays a wide role in its habitat
What is the main reason for resource partitioning among animals of the same species?
To reduce competition and coexist together
How does interspecies competition help limit populations of competing species?
By reducing competition for resources
What does biodiversity refer to?
The variety of species and ecosystems on Earth and the ecological processes of which they are a part
What are the 3 main components of biodiversity?
Ecosystem Diversity, Community Diversity, Genetic Diversity
Why is the highest level of biodiversity found near the equator?
Due to the abundance of sunlight and consistent climate, which support a wide variety of species and ecosystems
What is the role of variation in allowing closely related living things to survive in the same ecosystem?
It allows for the utilization of different niche spaces and resources, reducing competition
What is the definition of biology?
The study of living things
What does the term 'niche' refer to in the context of biological diversity?
The role and position of a species in its environment, including its interactions with the biotic and abiotic factors
What is the estimated number of identified plant and animal species out of the estimated 8.7 million?
1.2 million
Which of the following is not a component of biological diversity?
Ecosystem uniformity
What is the process by which the environment determines survival?
Natural selection
Who developed a system for classifying organisms based on physical structure?
Carolus Linnaeus
What is the expanded classification system based on Linnaeus' work?
5 kingdom classification: Animalia, Plantae, Fungi, Protista, Monera
Which of the following is an example of mutualism in symbiotic relationships?
Lichen in the arctic tundra
Study Notes
Biological Diversity and Interdependence
- The Amazon Rainforest's warm temperatures and ample sunlight support year-round plant growth
- Species distribution is not uniform across the Earth, with less diversity towards the poles
- There are an estimated 8.7 million plant and animal species, but only 1.2 million have been identified
- Biological diversity encompasses genetic, species, and ecosystem diversity
- Biological diversity is important for ecosystem stability, including disease resistance and adaptation
- Variability within species is crucial for survival in changing environments
- Natural selection is the process by which the environment determines survival, while artificial selection involves intentional breeding for desirable traits
- Carolus Linnaeus developed a system for classifying organisms based on physical structure
- Modern scientists expanded Linnaeus' system into the 5 kingdom classification: Animalia, Plantae, Fungi, Protista, Monera
- Interdependence among species is essential for survival and includes symbiotic relationships, competition, and predator-prey dynamics
- Symbiosis includes commensalism (one benefits, the other is unaffected), mutualism (both benefit), and parasitism (one benefits, the other is harmed)
- Examples of symbiosis include birds nesting in trees (commensalism), lichen in the arctic tundra (mutualism), and tapeworms in the human intestine (parasitism)
