Predator Prey Cycle Worksheet – Students learn about the different life cycles of various creatures. For example, a butterfly’s life cycle can be compared to the life cycle of a shark. They can also learn about the life cycle of an amphibian. This worksheet can help students learn how animals live. The worksheet can be completed by students individually or in a group.
The life cycle of a human
The human life cycle begins at fertilization when the egg cell of a woman fuses with a sperm cell of a man. On the sixth day, the single cell divides into a series of smaller ones that burrow into the mother’s womb. These cells form three layers and begin to bend into a complex shape called an embryo. In this stage, they also begin to differentiate from one another and form the fetal nervous system and circulatory system.
During this period, the human brain and body undergo many changes. While there are some differences between humans and apes in their lives, they all follow the same basic cycle. Apes, on the other hand, have a more erect body that allows them to show off their mobile hands. The food we eat supports a host of changes in the human body and brain after conception.
The human life cycle is organized around a series developmental stages and age groups. It also includes an infant phase. A human’s average life expectancy is approximately seventy-eighty years. However, this can vary depending on their health.
The life cycle of a butterfly
The Life cycle of a butterfly begins with the butterfly’s egg. This egg contains the nutrients the caterpillar needs to survive. Most butterflies lay their eggs on leaves. The eggs are small and may be round, oval, or cylindrical in shape. Monarch butterflies lay their eggs on the underside of plant leaves. They may be smooth or wrinkled. The eggs hatch within a few weeks.
After the butterfly emerges from its pupa, it injects its blood into its wings. Within a few hours the wings will be fully developed and the butterfly can fly. After the wings are fully developed, the butterfly will begin to search for food and a partner. After finding a mate, the butterfly will lay eggs on a leaf.
The next stage is the adult stage. The butterfly lays eggs in spring, summer, and fall. The female butterfly lays a large number of eggs at one time. Although the eggs are small, they can be very large. The caterpillar, also known as the larva, develops from the egg. It eats continuously during this period and sheds its skin up to five times. It stores food for the adult butterflies.
Sharks live a long life
Sharks have an extremely long life cycle. Sharks can live up to 15 years. Most sharks are born in coastal areas and remain close to the area where they were born until they are fully grown. During this time, sharks grow, mature, and reproduce. Sharks have two claspers, which allow them to grab onto a female and insert sperm.
The eggs and sperm are incubated by female sharks for several months before they reach full term. The mother keeps the young sharks inside for about a year before they are born. Some species of sharks exhibit cannibalism, where the first pup is born alive and eats other eggs or pups. These ovoviviparous species have a variable gestation period, which can vary from several months to up to two years. Asexual reproduction is also possible in some species.
Sharks have excellent hearing and are able to detect incoming sound waves from their prey. The dorsal fins on their heads are located on either side. Their lateral line system consists of thin canals filled with water and is attached to nerves that send signals to the brain.
Amphibian life cycle
The life cycle of most amphibians is complex, with a larva becoming an adult and then a larva becoming a larva. These life cycles are governed by hormones and the environment. Thyroid hormones and corticosteroids produced by interrenal glands are the primary morphogens in amphibians and are dependent on input from the hypothalamus and pituitary glands. Ultimately, the hypothalamus regulates the activity of both the thyroid gland and the pituitary gland.
Amphibians are unique in their life cycles. They can reproduce in both water and on land. The life cycle of a frog begins with sexual reproduction, in which the male entices the egg-carrying females to mate. The females then release their eggs into the water where the males fertilize them with sperm. Most species of amphibians reproduce by external fertilization.
Most species of frogs lay their eggs in peaceful water, which protects them from predators. Some species, however, stay with the eggs to care. The eggs become tadpoles once they are fertilized. Within one to three weeks, the tadpoles are ready for hatching.
