Answer:
This statement is false.
Explanation:
Producers (namely mosses and liches) are the first organisms to reenter an ecosystem and are known as "pioneer species". They are proceeded by (in this order) small plants, shrubs, bushes, and climax communities (i.e. large trees). Only then do consumers once again become part of the ecosystem. For all of these reasons, the statement presented in this question is false.
Answer:
Wildebeest and Zebra.
Explanation:
Wildebeest and Zebra are the hunts which gives huge amount of energy and lowest cost of energy because Wildebeest gives 25000 available energy and 10000 energy cost to hunt and 15000 amount of energy remain while Zebra gives 170,000 while 55000 energy spend on the cost to hunt and 115000 is available energy to the lion that is enough for the lion per day energy requirements.
<h2>
Answer:</h2>
Option C) The organism can move around its environment using a flagellum.
<h2>
Explanation:</h2>
Out of four options option C) matches the most.
- Although most of the bacteria are Heterotrophs but a variety of species of them are Autotrophs making their own food. Hence option a) is incorrect.
- Bacteria belong to prokaryotes which means they do not have a well defined membrane bound nucleus. hence option b) is also incorrect.
- Most of the bacteria can move through flagella only a few species do not have flagella. Hence this option matches the most.
- Bacteria are unicellular organism and none of the species of bacteria is multicellular. Hence option d) is incorrect.
Resut: Option C) matches the most for defining bacteria.
Answer: The theory of cheek cells is used for the identification of cheek cells.
Explanation:
The cells of cheek do not have cell wall. They have a cell membrane which allows on certain molecules to pass through it. The nucleus is located centrally in the cheek cells and it stores the DNA. It can be stained with the help of the methylene blue reagent. It appears blue in color which can be observed under the microscope. The cheek cells can be isolated from the buccal cavity by using cotton buds and cotton swabs can help in isolating the cells.
