* Plants:
* Resource Availability: Plants can adjust their seed production based on factors like water, nutrients, sunlight, and pollinators. If resources are scarce, they may produce fewer, smaller seeds to conserve energy.
* Environmental Stress: Factors like drought, extreme temperatures, or herbivory can also trigger changes in seed production. Some plants even have adaptations to delay seed production until more favorable conditions arise.
* Animals:
* Food Availability: Animals, particularly those with seasonal breeding cycles, adjust their egg production based on food abundance. A plentiful food supply often leads to larger clutch sizes (number of eggs).
* Predator Pressure: Predation can also influence egg production. Some animals may produce more offspring if predation rates are high, increasing the chances that some will survive.
* Environmental Conditions: Factors like temperature, humidity, and habitat availability can also affect egg production in animals.
Important Note: The degree to which plants and animals adjust seed/egg production varies greatly depending on the species and the specific environmental conditions. Some species are more adaptable than others.
