Why aren’t the snakes growing and thriving in the forest ecosystem?

wolverine [178]

Answer:

Arboreal or tree dwelling snakes possess prehensile tails, with which they grip branches as they hunt in the forest canopy. Forest snakes, which live and hunt principally in the trees, use their body muscles and ribs to easily move along branches in the forest canopy.

Explanation:

Around the world, snake populations are in decline because of habitat destruction, disease, over-harvesting, invasive species, and even climate change. These combined threats have brought some snake species ever closer to the brink of extinction.

The widespread disappearance of snakes will be one impact of climate change that some people may find it hard to regret. But as vital predators in sensitive habitats such as rice fields, their decline will have wider ecological consequence, say scientists.

Que efecto tiene la cantidad de agua en el crecimiento de las plantas

mel-nik [20]

Question in English:

What effect does the amount of water have on plant growth?

Answer:

Necessary for photosynthesis - food production to provide energy for growth
Helps in transport of nutrients and other substances
Helps the plant remain upright

Explanation:

Photosynthesis is the production of sugar by plants. It requires sunlight, water, and carbon dioxide. The sunlight energy breaks the water molecule into hydrogen ions and oxygen. Oxygen is released, and the hydrogen ions are used to provide energy to power the reactions that make sugar from carbon dioxide. These sugars are needed to provide energy for all plant processes including growth.

Water is also required to transport nutrients and other substances around the plants via the plant transport system. The substances are dissolved in water.

Finally, water is needed to remain turgor pressure in the cells. This gives the plant structure and helps it to remain upright to absorb more sunlight.
