It’s a Vibe… an Ecological Vibe
This biome has the highest biodiversity on Earth and is located near the equator with high precipitation.
What is the Tropical Rainforest?
This stage is characterized by high birth rates and high death rates, resulting in low population growth.
What is Stage 1 of the Demographic Transition Model?
This HIPPCO factor involves the destruction or splitting of ecosystems into smaller patches.
What is Habitat Fragmentation?
This process converts atmospheric nitrogen gas (N₂) into ammonia (NH₃) by bacteria.
What is Nitrogen Fixation?
This gas makes up about 78% of Earth’s atmosphere.
What is Nitrogen Gas?
This biome is dominated by grasses, has seasonal rainfall, and supports large herbivores like elephants.
What is the Savanna?
In this stage, death rates decline due to improvements in sanitation and medicine, causing rapid population growth.
What is Stage 2 of the Demographic Transition Model?
This occurs when non-native species outcompete native species for resources.
What are Invasive Species?
This process converts ammonia into nitrites (NO₂⁻) and then nitrates (NO₃⁻).
What is Nitrification?
This gas makes up about 21% of the atmosphere and is essential for cellular respiration.
What is Oxygen Gas?
This biome receives less than 25 cm of precipitation annually and has organisms adapted to conserve water.
What is the Desert?
This stage sees declining birth rates as access to education and contraception increases.
What is Stage 3 of the Demographic Transition Model?
This HIPPCO factor increases resource demand and habitat pressure due to a growing number of humans.
What is Human Population Growth?
Plants absorb this form of nitrogen most readily from the soil.
What are Nitrates?
This atmospheric layer contains the ozone layer, which absorbs harmful UV radiation.
What is the Stratosphere?
This biome has nutrient-poor soil, coniferous trees, and long, cold winters.
What is the Taiga?
Low birth and death rates characterize this stage, resulting in a stable or slow-growing population.
What is Stage 4 of the Demographic Transition Model?
This includes substances like pesticides, plastics, and heavy metals that harm ecosystems.
What is Pollution?
This process returns nitrogen gas (N₂) back to the atmosphere from soil bacteria.
What is Denitrification?
Weather events such as storms and clouds occur in this lowest layer of the atmosphere.
What is the Troposphere?
Permafrost is a defining feature of this biome, limiting plant growth and drainage.
What is the Tundra?
Some countries experience population decline in this stage due to very low birth rates.
What is Stage 5 of the Demographic Transition Model?
This HIPPCO factor alters temperature and precipitation patterns, affecting species distribution.
What is Climate Change?
This process converts organic nitrogen in dead organisms into ammonium (NH₄⁺).
What is Ammonification?
This gas, though present in small amounts, is a major contributor to the greenhouse effect.
What is Carbon Dioxide?
