An ecological deficit occurs when the Footprint of a population exceeds the biocapacity of the area available to that population. Conversely, an ecological reserve exists when the biocapacity of a region exceeds its population's Footprint. ... The Ecological Footprint is usually measured in global hectares.
Ecological reserves are areas selected to preserve representative and special natural ecosystems, plant and animal species, features and phenomena. Scientific research and educational purposes are the principal uses of ecological reserves.
Asteroids rarely pass close to Earth
Stage 1: High Equilibrium
High birth rate and high death rate
Stage 2: Early Population Increase
Decreasing death rate, constant birth rate
Stage 3: Late Population Increase
Death rate stabilizes at a lower amount, birth rate decreases
Stage 4: Low Equilibrium
Low birth rate and low death rate
Answer:
Convergent plate boundaries
