How does energy change as it moves through the ecosystem?

Biology

Mkey [24]3 years ago

Answer:

A: The energy in most ecosystems flows through the food chain. In terrestrial ecosystems and most marine ecosystems, the energy flow starts in green plants that harvest some of the sun’s energy. The plants are then consumed by animals, bacteria and other creatures, which are themselves eaten by other creatures.

Answer:

All living things need energy. They need it to power the processes of life. For example, it takes energy to grow. It also takes energy to produce offspring. In fact, it takes energy just to stay alive. Remember that energy can’t be created or destroyed. It can only change form. Energy changes form as it moves through ecosystems.

serious [3.7K]

Answer:

The correct answer is "two examples of how radar installations might cause hazard to human health are: decreased ability to perform mental tasks and induction of eye cataracts".

According to the World Health Organization electromagnetic fields below 10 Gigahertz of power do not represent a threat to human health, which make most radar installations safe for operation. However, some studies performed in primates by the exposure of increasing levels of electromagnetic fields have shown that they can developed a decreased ability to perform mental tasks and induction of eye cataracts.

What is the major function of a leaf
ANEK [815]

Answer:

Photosynthesis

Explanation:

The leaf (from Latin fŏlĭum, fŏlĭi) is the vegetative and generally flattened organ of vascular plants, specialized mainly to perform photosynthesis. The morphology and anatomy of stems and leaves are closely related and, together, both organs constitute the stem of the plant.

Typical leaves - also called nomophiles - are not the only ones that develop during the life cycle of a plant. From the germination, different types of leaves follow each other - coiled, primordial leaves, prophilic, bracts and antophiles in flowers - with very different forms and functions.

A nomophile usually consists of a flattened sheet, a short stem - the petiole - that joins the sheet to the stem and, at its base, a pair of appendages - the stipules. The presence or absence of these elements and the extreme diversity of forms of each of them has generated a rich vocabulary to categorize the multiplicity of types of leaves presented by vascular plants, whose description is called foliar morphology.
