Second is that cloned nature of colonies is disadvantageous if disease is present.

Solution
Hydra reproduces by budding.
Hydra can also reproduce sexually.
Advantages: First advantage is that this form of reproduction can form many new organisms very
quickly. Second advantage is that hydra don't move around very much, so they conserve a lot of
energy.
Disadvantages: First is It is relatively simple organism. Second is that cloned nature of colonies
is disadvantageous if disease is present.
Advantages: It has been observed in several studies that earthworms are utterly without fenders,
and it is that this enables them to move through earth at reasonable speed.
Disadvantages: They move slow in land, so can easily be preyed upon often.
Advantages: There role in ecosystem is beneficial. Grasshopper serves as a food for many
predators including birds and lizards.
Disadvantages: First is Grasshoppers can create nuisance to people when they invade homes.
Second is that they can destroy pests.
Advantages: It s very beneficial as dietary source. It is rich in proteins, low in fats and excellent
source of omega 3 fatty acids.
Disadvantages: One disadvantage of fish farming is related to the environment. It can pollute
water.AnimalType of circulatory systemsOutstanding

An earthworm circulates blood exclusively through vessels. There are three main vessels that

appendages called setae which are used by the animals as anchor during locomotion.
Advantages: It has been observed in several studies that earthworms are utterly without fenders,
and it is that this enables them to move through earth at reasonable speed.
Disadvantages: They move slow in land, so can easily be preyed upon often.GrasshopperThe
circulatory system in grasshopper is "open" which means the blood flows into open spaces and
sinuses.They have large eyes and coloring that matches their environment.
Advantages: There role in ecosystem is beneficial. Grasshopper serves as a food for many
predators including birds and lizards.
Disadvantages: First is Grasshoppers can create nuisance to people when they invade homes.
Second is that they can destroy pests.FishFish have a single systemic circuit for blood, where the
heart pumps the blood to the gills to be re-oxygenated, after which the blood flows to rest of the
body.Fish are cold blooded animals, so their internal body is influenced by temperature.
Advantages: It s very beneficial as dietary source. It is rich in proteins, low in fats and excellent
source of omega 3 fatty acids.
Disadvantages: One disadvantage of fish farming is related to the environment. It can pollute
water.FrogThe circulatory system in frog is closed. The frog has a unique heart. The frog's heart
has three chambers: two atria and. a single ventricle.Frogs have a very good eyesight. Frogs also
have amazing sense of smell.Advantages: They are in the middle of the food chain and provide
a very efficient transfer of solar energy. They play an important role in consuming insects and
are an important food sources for birds, snakes , etc.
