Ecology and ecosystems
What is an organism
An organism is a single living individual
Phosphorus cycle
weathering of rocks and minerals releases phosphate ions, which plants from the soil then take up.
Ocean acidification due to burning fossil fuels
occurs when carbon dioxide (CO2) from these fuels dissolves into the ocean and lowers its pH, making it more acidic.
Renewable energy sources
solar, wind
What is Primary succession
Colonization by lichens
What is a population
all the inhabitants of a particular town, area, or country.
10% rule of energy transfer between trophic levels
Only 10% of the energy available at one trophic level is transferred to the next.
Consequences of deforestation
loss of biodiversity
Benefits of solar panels
reduced environmental impact
How does Secondary succession happened?
occurs after disturbances like forest fires
What would be on top of this food chain.
Deer, plant, wolf , decomposers
Wolf
Law of Conservation of Energy
energy cannot be created or destroyed, but rather, it can be transformed from one form to another or transferred from one object to another.
Sustainable forestry practices
selective logging
Disadvantages of biofuels
deforestation
Positive human influence on succession
reforestation
Role of decomposers in nutrient recycling?
Breaking down dead organic matter, releasing essential nutrients back into the environment.
Effects of invasive species on food webs
forcing native species to eat less desirable food sources, creating divergent biological communities, and potentially replacing or displacing native species
Negative effects of urbanization
habitat loss, fragmentation, and degradation.
Risks of nuclear energy
radioactive waste
Changes in biodiversity during succession
generally increasing as the ecosystem matures.
Impact of keystone species on ecosystem stability
maintaining stability and biodiversity
What does energy flow mean?
the transfer of energy from one entity to another, primarily within ecosystems.
Environmental impact of mining
water contamination
Sustainability of renewable energy sources
Renewable energy is considered sustainable because it is derived from natural sources that are replenished by nature and do not deplete like fossil fuels.
Importance of genetic diversity in adaptability
allows for more individuals to be well-suited to new conditions, increasing the likelihood of survival and reproduction
