What is ecology?
Ecology is the study of how living things interact with each other and their environment.
Explain the difference between a habitat and a niche.
A habitat is where an organism lives, while a niche is how it lives in that habitat.
What are biotic factors and abiotic factors (give examples of each)?
Biotic factors are living things, like plants and animals. Abiotic factors are non-living things, like sunlight and water.
What are the ecological levels of organization in order from the simplest to the most complex
From simplest to most complex: individual, population, community, ecosystem, biome, biosphere.
Name some greenhouse gases.
Carbon dioxide (CO2)
Methane (CH4)
Nitrous oxide (N2O)
Water vapor (H2O)
Ozone (O3)
Chlorofluorocarbons (CFCs)
What is biodiversity?
Biodiversity is the variety of life on Earth, including different species and ecosystems.
What is the greenhouse effect?
The greenhouse effect is the process that warms the Earth’s surface
How is the environment negatively and positively affected by industrial technology and agricultural technology?
Industrial and agricultural technologies can harm the environment through pollution and resource depletion, but they can also benefit it by increasing efficiency and food production, as well as promoting renewable energy.
What are some examples of alternative energy?
Examples of alternative energy include solar power, wind power, hydropower, geothermal energy, biomass, and tidal power.
What is a Detritivore?
Detritivore: An organism that feeds on dead and decaying organic matter, such as leaf litter and dead animals.
What is the ultimate source of energy in ecosystems?
The Sun
Explain the difference between an autotroph and a heterotroph.
Autotrophs make their own food, while heterotrophs consume other organisms for food.
What is a Decomposer
Decomposer: Organisms, such as bacteria and fungi, that break down organic matter into simpler substances, helping to recycle nutrients in ecosystems.
What is the difference between a food chain and a food web?
A food chain is a simple sequence of who eats whom in an ecosystem, while a food web shows all the interconnected food chains in an ecosystem.
What is nitrogen used for in our bodies?
Nitrogen is used to build proteins, DNA, and ATP, essential for cell function and energy transfer in the body.
