I recall that Professor Kwang had observed amoebas that had cannibalized bacteria cells. The bacteria were slaughtering the amoebas, but somehow some survived. This particular group of amoebas contained bacteria that thrived inside it. Hence the name, endosymbiosis. However, this lucky group and it's offspring could not survive without bacteria.

In 1987, Professor Kwang Jeon of the University of Tennessee observed a number of amoebas (single-celled eukaryotes) that had ingested bacteria cells. The bacteria were killing off most of the amoebas, but a small number of the amoeba survived and returned to their normal modes. However, the invading bacteria were still present within surviving amoebas. Jeon continued to experiment with the amoebas and discovered that these surviving amoebas, and their offspring, could not survive without the bacteria. Jeon's discovery and experimentation proves it is possible for a cell to become dependent on an invading organism.

if a bunny eats grass that has 100 units of energy and the bunny get 10% how much is passed on to the next animal .

Vikentia [17]

Answer:

This is an excellent source!

Example- The producer receives its energy from the sun, which is the ultimate source of energy. Meaning all the energy we use comes from the sun. Like I said earlier, the energy from the corn moves into the mouse. Not all the energy that the corn has is able to be transferred into the mouse, only about 10% of the available energy is transferred to each trophic level. A trophic level is the position an animal occupies in a food chain. And again only about 10% of energy is transferred from the mouse to the owl.

The introduction of the Asian Clam in Lake George is an example of an Invasive Species.

Asian Clam are small in size, hardly 1.5 inches long. However, they can reproduce very quickly without the need for a partner. A single clam can give birth to hundreds of offspring in a single day without a mate.

Asian Clam is extremely unpleasant for most fresh water bodies since it excretes nutrients such as nitrogen.

This helps in the development of algae and gives off a foul stink.
