Reproductive Success in Animals and Plants

Pollination in flowering plants

• the transfer of pollen for fertilization

• the process of photosynthesis

• the absorption of water by roots

• the production of seeds in fruits

Adaptive value of animal mating calls

• mates

• signals fitness

• increases reproductive success

• attracts predators

Impact of animal territorial behavior on reproduction

• Increases competition for food

• Resources, attracts mates, increases offspring survival

• Reduces genetic diversity

• Decreases mating opportunities

Bright flower colors

• Attract pollinators like bees and birds

• Repel insects and pests

• Indicate the age of the flower

• Provide shade to the plant

Parental care in mammals

• offspring survival by protection and feeding

• increased competition among siblings

• reduced genetic diversity

• enhanced mobility of the young

Animal migration

• to better breeding or feeding areas

• to escape predators

• to find new habitats

• to follow seasonal weather patterns

Seed dispersal structures

• seeds spread away from parent plant

• seeds remain close to the parent plant

• seeds are eaten by animals

• seeds grow into new plants immediately

Reason for synchronized spawning in fish

• Increases competition for resources

• Fertilization rates, reduces predation risk

• Enhances individual growth rates

• Decreases genetic diversity

Camouflage in animal mating

• from predators, increases mating success

• is primarily for temperature regulation

• is used to attract more predators

• is a method of communication between species

Nest building in birds

• provides shelter for eggs and young, aids survival

• is primarily for decoration

• is only done during mating season

• is not important for survival
