Community Ecology Quiz

The study of interactions between populations of different species within a defined area, focusing on biodiversity.

Temperature is a key factor that affects where different species can thrive, causing biodiversity to vary across the globe.

Rainforests have the highest levels of species richness and complex interactions, making them the most productive.

The text identifies habitat loss as the most significant factor currently driving species to extinction.

Mutualism is an interaction where both species involved benefit from the relationship (+/+).

Although 'Bees' is listed in the content, Mycorrhizae, fungi, live in symbiosis with plant roots, aiding nutrient absorption, while the plant provides sugars.

Autotrophic organisms, like plants, are capable of producing their own food through photosynthesis.

Only about 10% of the energy stored in one trophic level is converted to biomass in the next level.

Primary succession is the colonization of new habitats devoid of life, where soil has not yet formed.

Dominant species are the most abundant in a community and exert a strong influence on the community structure.

Keystone species play a critical role in maintaining the structure and function of an ecosystem.

Biodiversity hotspots are regions with high species richness that face significant threats of habitat destruction.

Low genetic variability can reduce a population's ability to adapt to environmental changes, leading to lower fitness.

Small populations with low genetic variability can become trapped in a cycle of inbreeding and loss of adaptive potential.
