Ecosystems and Energy Flow
What process converts solar energy into chemical energy stored in glucose
What is photosynthesis
What does HIPPCO stand for in relation to threats to biodiversity?
What is habitat loss, invasive species, population growth, pollution, climate change, and over exploitation.
What type of growth curve shows population growth with limited resources?
What is logistic growth (S-curve)?
What type of pollution is caused by excess nitrogen and phosphorus in water bodies?
What is nutrient pollution (eutrophication)?
What is the primary greenhouse gas released from burning fossil fuels?
what is carbon dioxide
Which level in an energy pyramid contains the most available energy?
What is difference between species richness and species evenness?
What is richness is the number of species, while evenness is the distribution of individuals among species?
Which r-selected trait makes a species more likely to rebound after disturbance?
What is a high reproductive rate or rapid maturity
What are two health effects of exposure to lead or mercury?
What are nervous system damage, developmental delays, or cognitive impairment
What human activity is the largest source of anthropogenic methane?
What is livestock agriculture (enteric fermentation)?
What is lightning or nitrogen fixing bacteria
Define a keystone species and give one example
What is a species that has a large effect on ecosystem structure, such as sea otters or wolves.
Define carrying capacity
What is the maximum population size that an environment can support without degrading resources
Describe the difference between point source and non point source pollution.
What is a point source comes from a single identifiable source, non-point source is diffuse and comes from many sources.
Explain the difference between weather and climate
What is weather is short term atmospheric conditions, while climate is long term patterns.
In which type of biome would you expect to find the highest net primary productivity?
What is a tropical rainforest?
What is the purpose of a wildlife corridor?
What is to connect fragmented habitats and promote gene flow
What does a population pyramid with a wide base suggest
What is a rapidly growing population with high birth rates?
What is the main goal of the Clean Water Act?
What is to restore and maintain the integrity of U.S. waters by reducing pollution
What is one environmental consequence of melting permafrost?
What is the release of methane or carbon dioxide, which accelerates climate change
Describe what happens during ammonification in the nitrogen cycle.
What is decomposers converting organic nitrogen into ammonium (NH4+)
Explain how an island's size and distance from the mainland affects species richness, according to island biogeography?
What is larger islands and closer island support more species due to more resources and higher immigration rates
Describe two density dependent limiting factors
What are competition, disease, or predation
What is it can contaminate groundwater if not properly contained or treated
Describe how ocean acidification occurs and the ecological impact.
What is CO2 dissolves in seawater forming carbonic acid, which lowers pH and harms shell-forming organisms like corals and mollusks?
