  • life cycle of a butterfly starts of with finding a mate
  • butterfly - when the sperm cell and egg cell unite internal fertilization occurs
  • the butterfly then lays her eggs on leaves or stems
  • butterfly- when the egg hatches the larva called caterpillar feedss on leaves
  • the larva will soon find a place to rest to evolve into its pupa stage
  • in the pupa stage the caterpillars body shortens and thickens it forms a cocoon
  • the larva changes inside the cocoon and then emerges as a adult butterfly
  • the life cycle of mosquitoes starts with finding a mate, the eggs are then fertilized internally
  • the zygote will then develop into a embryo and the female mosquito sucks blood as a source of energy for egg development
  • then the female mosquito will lay her eggs in stagnant water the eggs will then hatch in 2-3 days
  • when the mosquito egg hatches a larva called wriggler lives in water and feeds on organic materials
  • the larva will develop into the pupa stage or tumbler in 2-7 days the mosquito emerges
  • Frogs sexual reproduction and fertilization occur externally
  • During mating season the male frog vocalizes to call the female, the the female vocalizes her response
  • the female frog releases eggs and the male frog releases the sperm
  • frogs fertilized eggs are covered with jellylike substance that keeps them moist
  • a frog egg then hatches into a tadpole which feeds on algae and rotting vegetation
  • transformation begins when the tadpoles back legs start to grow eventually the front legs form
  • A froglet develops a pair of lungs then its tail disappears and then becomes a adult frog
  • Life cycle of a dog internal fertilization occurs after mating it will then continue its embryonic development while inside the female's body
  • then the female dog gives birth to a puppy then the puppy grows up to become an adult dog
  • life cycle of a chicken, chickens are oviparous animals the eggs are fertilized internally but the embryo development take place outside the female's body the eggs are laid and hatch into new hatchlings
