Answer:
Living organisms that are made up of cells that have nucleus are called EUKARYOTES
Explanation:
Living organisms are grouped into two according to the composition of their cell components. These include:
--> The PROKARYOTES: these organisms possess a very simple cell structure with no definite nucleus. Example of such organisms include the eubacteria (that is, 'true' bacteria), archaebacteria ( which is also a type of bacteria) and blue green algae.
--> The EUKARYOTES: these organisms possess a complex cell structure with a well defined nucleus. The nucleus is found enclosed within a nuclear membrane. Hereditary materials are located within the nucleus and the cell has other components known as the cell organelles. These organelles include the mitochondria, Golgi apparatus, Endoplasmic reticulum, Ribosome, lysosomes. Example of eukaryotes are the animals, plants, fungi, and protists.
Therefore, Living organisms that are made up of cells that have nucleus are called EUKARYOTES
Answer:
The size is reduced as 80-95% of the available energy at one trophic level is not transferred to the next
Explanation:
There is loss of energy as it is transferred between trophic levels. The decrease in energy as it moves up the pyramid is due to energy loss as metabolic heat when one organism is consumed by another from the next level as it moves up the trophic levels.
