Answer:
(B) Energy transfer between trophic levels is almost always less than 20% efficient.
Explanation:
The ultimate source of energy on the Earth is the Sun. The energy coming from the Sun is captured by green plants by the photosynthesis. During photosynthesis sun energy is fixed into chemical energy (carbohydrate). So, in an ecosystem energy flow is unidirectional (from sun to the green plants). The fixed chemical energy from green plants is transferred to the herbivores then to carnivores through food. When one organism eats another organisms, only 10 % of the energy present in the organism is transferred as a food for the next organism and a large amount of energy is lost as heat into the environment. Thus, energy keeps on decreasing when stored energy moves from producers to top consumers. Thus, less than 20% energy transfer limits the trophic levels in most of the ecosystem.
Water escapes from the pores in plant leaves because of evaporation. This water is what keeps the vacuoles in the cells full and shaped, so the vacuoles are like deflating water balloons
Answer:
A) Biotic
Explanation:
It's definitely not abiotic and nonliving because they are living and who would categorized 'excretions of living organism' "living".
Answer:
Wound healing is a process to regenerate cells at the site of an injury or infection. Asexual reproduction is a process in which daughter cells are produced from a single cell or organism.
The wound healing process is similar to asexual reproduction because both the processes use mitosis for cell division. As a result of mitosis, two daughter cells are produced which are identical to the parent cells. Hence, during wound healing and asexual reproduction, the same cells as the parent cells are produced.
The appropriate response is cilia. Cilia are little hair-like structures on the surface of the cell. The hairs clear hair, bodily fluid, caught tidy and microscopic organisms up to the back of the throat where it can be gulped.
Cilia are found in the coating of the trachea (windpipe), where they clear bodily fluid and earth out of the lungs. In female well evolved creatures, the beating of cilia in the Fallopian tubes moves the ovum from the ovary to the uterus.
