tensa zangetsu [6.8K]

Habitats of the plants:

X : winter or cold mountainous habitat

Y : desert habitat

Z:  Aquatic habitat

Explanation:

The X plant leave morphology suggests that thick wax coating of leaf helps it to retain water in it. Such plants are called conifers. They are not shed every year so suitable for sunlight to be captured for photosynthesis. In cold regions heavy wind happens cone like leaf is able to resist the winds and prevent it from falling. The cone like structure of leaves help them let the snowfall.

The plant Y leaves and root morphology suggests that it is well suited for dry lands or desert as where less water is there. They store water for longer time when it rains because of the extensive root system. The spine leaves help in reduced transpiration as water scarcity is there.

The plant Z leaves morphology suggests that thin and ribbon structure leaves can help them resist the pressures of flowing water as there are air space in the leaves which provide buoyancy to the leaves.

PLZ HELP ME IT'S FOR A BIG PROJECT!!! Describe a seahorse (physical appearance, habitat, function, history, etc.).
storchak [24]

The seahorse is found in many different locations around North and South  America. They are typically located in the shallow tropical waters that are quite warm. They will be found living along the coral, the sea grass, and the mangroves. In Europe they are known to reside in the Thames estuary. Many of the larger species are living in the Mediterranean Sea.

Many species of seahorses are very territorial. The males often have about 11 square feet of territory. The females have up to 1,100 square feet. What they live though will influence how much area they have. In many regions that habitat range has gotten smaller and smaller.

In captivity the seahorses will be limited to a large aquarium. This can be a huge change in home range habitat for them. That is why the stress levels are very high and the survival rate low. Young in a captive state are more likely to do well because they haven’t become accustomed to the wide territory.

As a result the seahorses living in a given area have become more aggressive. They have also suffered from higher stress levels and more forms of disease. The aggressive behavior is typically when males are looking for females that they can mate with. It is also common when they are fighting for territory or food and that extends to both genders.
