Study Notes
Arctic Winter Survival
- As summer ends, Arctic plants cease photosynthesis and enter dormancy.
- Many plants survive winter in seed form.
- Some animals hibernate, conserving energy and not eating during winter months.
- Arctic foxes struggle to find food in winter's harsh conditions.
Seasonal Reproduction
- Plant-eating animals in the Arctic time their reproduction to coincide with increased plant availability in summer.
- Offspring are born during periods with abundant food and energy storage molecules.
- Animals convert carbon from glucose into fats for energy storage.
- Arctic predators also synchronize reproduction with seasonal food availability, leading to a population surge.
Migration Patterns
- Summer brings an influx of migratory birds and other animals to the Arctic for feeding and reproduction.
- Many native Arctic animals either perish or leave in search of food during the harsh winter.
Rainforest Canopy Dynamics
- Rainforest canopies receive ample sunlight, supporting diverse species.
- The canopy is the primary habitat for many rainforest organisms, including birds and plants.
- Birds in these ecosystems actively feed on fruits and insects, engage in mating, and build nests among the leaves.
- Plants thrive in the treetops, utilizing high tree branches as growth platforms.
