- Growth is the process of increasing in size, weight, and complexity over time.
- Reproduction is the process by which organisms produce offspring.



- Both growth and reproduction require energy.
- The energy available to an organism is limited, so energy allocation to growth and reproduction is a trade-off.
- If an organism allocates energy to growth, it will have less energy available for reproduction, and vice versa.



- Growth and reproduction also require different resources.
- Growth requires resources such as nutrients, water, and building blocks for cells and tissues.
- Reproduction requires resources for gamete production, mating, and offspring care.
- If an organism allocates resources to growth, it will have fewer resources available for reproduction, and vice versa.



- Different organisms have different life history strategies, or ways of allocating energy and resources to growth and reproduction.
- Some organisms, such as annual plants, allocate most of their energy and resources to reproduction and have a short lifespan.
- Other organisms, such as trees, allocate more energy and resources to growth and have a longer lifespan.
- These life history strategies are shaped by environmental factors such as predation, competition, and resource availability.



- Growth and reproduction are mutually exclusive events because they require energy and resources that are limited and must be allocated between the two processes.
- Different organisms have different life history strategies that reflect their trade-offs between growth and reproduction.
