Ecology & Ecosystems
A simple, linear sequence of energy flow from a producer to one consumer, and then another.
What is a food chain?
What area has the most biodiversity?
What is the tropical rainforest?
What is the process called when natural habitats are broken up into smaller, isolated patches of land (e.g., building a highway through a forest)?
A. Habitat degradation
B. Habitat fragmentation
C. Biomagnification
D. Ecological succession
B
The process by which a forest grows back after a massive forest fire
What is secondary succession?
this term refers to the variety of species in a specific area
What is biodiversity?
What does the term "overexploitation" refer to in the context of biodiversity?
Overharvesting or hunting beyond sustainable yields that lead to population crashes.
the study and implementation of methods to protect biodiversity
What is conservation biology
This is a natural environment that acts as a "home" for specific plants, animals, or other organisms. It provides exactly what is needed for survival: food, water, shelter, and proper space.
What is a habitat?
Genetic diversity describes the variation of genes or differences in _______ (found in the cell's nucleus) among individuals within species and populations.
The primary cause of the current, modern-day mass extinction Earth is experiencing.
What are humans?
This type of protected area strictly limits human development to preserve critical ecosystems and wildlife.
What are nature reserves or national parks?
This type of symbiotic relationship benefits both participating organisms
What is mutualism?
This is one way human's benefit from biodiversity?
What is medicine?
A. It makes the ecosystem more stable and resistant to disease.
B. It makes the ecosystem less stable, meaning a change to one organism has a much greater impact on the whole system.
C. It has no measurable effect on ecosystem stability.
D. It forces the ecosystem to completely restart the process of evolution.
B
This concept, first described in 1968, explains the overuse and depletion of shared, unregulated environmental resources.
Tragedy of the Commons
Strips of natural habitat that connect isolated wildlife populations separated by human activities (like highways or developments), allowing animals to safely migrate and breed.
What is a habitat corridor?
The classification of consumers, like fungi and bacteria, that break down dead organic matter and return nutrients to the ecosystem.
What are decomposers?
The number of different organisms in an ecosystem is the species...?
A. Richness
B. Abundance
A
List 4 causes of biodiversity loss.
1) Pollution and climate change
2) Habitat loss
3) Over exploitation
4) Invasive species
A species whose introduction causes or is likely to cause economic harm, environmental harm, or harm to human health
What is an invasive species?
a strategic, written document that outlines how specific land will be managed, enhanced, and monitored to support target wildlife, plant species, or ecosystems.
What is a habitat management plan?
