Natural Process Diagrams: The Life-cycle of Frogs

 

The diagram illustrates a frog’s physical development. Overall, the life cycle is long and complex, consisting of 10 stages. It begins when an adult frog lays eggs and concludes when a young frog matures into a fully grown adult.

In the first half of the process, the frog begins life as a tadpole. First, the eggs develop into embryos with the undeveloped tadpole growing inside. When the tadpole is ready, it hatches from the embryo and clings to underwater plants. In the next stage, the tadpole develops gills, which allow it to breathe underwater, and its tail grows longer.

In the second half of the process, the tadpole begins to transition into a frog. Rear legs start to appear at the back of the animal’s body. Then, while sustaining itself on food stored in its tail, front legs begin to grow, and the tail begins to decrease in size. By this stage, the amphibian is more recognizable as a frog than in the previous stages. When the tail has completely vanished, the animal becomes a young frog. In the final stage, the young frog matures into an adult frog, ready to lay eggs and begin the process again.

Discuss Both Sides and Give Your Opinion

With increasing numbers of species becoming endangered or going instinct, examining approaches to the preservation of wildlife has become a vital issue. While some argue that zoos are cruel and inhumane institutions that contribute to the suffering of animals, I posit that animal welfare and preservation is promoted through the proliferation of zoos. In this essay, I will critically discuss both views and state my opinion.

In the first instance, captivity can have a detrimental effect on the wellbeing of animals. Many animals have vast territories in the wild and enjoy large open spaces. When animals are confined in small cages or pens it puts unnecessary stress on them, which can create numerous health problems. Furthermore, the conditions of some of cages can squalid and unhygienic, further adding to the animal’s distress and wellbeing. In Syria, Thailand, and Romania, for example, PETA and other animal rights groups have had to rescue numerous animals from zoos due to their extremely poor conditions.

On the other hand, zoos run conservation programmes that help protect endangered species from extinction. By raising funds through zoo admissions and charitable donations, zoos are able to provide a safe environment for animals that would offer be targeted by poachers or suffer from habitat loss. Additionally, these initiative often involve breeding programmes to help increase their numbers. Consider the panda for instance,. In China, zoos have been an integral part of preserving these animals following the loss of the bamboo forests where they live, and have successfully bred the species in captivity.

In summation, while animals would be better off in the wild in an ideal world, I believe the threat from poachers and habitat loss make zoos a necessary evil that protects endangered species from extinction. If governments create legislation that ensure safe, clean, and adequate environments, then many of the downsides of zoos can be addressed, allowing animals in captivity to enjoy a better quality of life.
