Explanation:
Answer: herbivore, eukaryote, primary consumer
Explanation:
The red squirrel can be described by the following features.
1. Herbivore: A herbivore is an animal which is dependent upon the plant and their products for it's food requirement. Here, the red squirrel is the herbivore because it is dependent upon the spruce tree seeds for their food requirement.
2. Eukaryote: A eukaryotic organism is the one which has well define nucleus and encloses the genetic material in the nucleus. The red squirrel is a complex eukaryotic organism.
3. Primary consumer: In a food chain a primary consumer is an organism which is dependent upon plants and their food products for energy and food needs. The red squirrel is the primary consumer this is because of the fact that it consumes on the seeds of the spruce trees.
A. The argument recently in science has been the rising levels of carbon dioxide which is major component of climate change
Answer:
The correct order from smallest to largest are: Molecule, Cell, Tissue, Organ, Organ system and Organism.
Explanation:
- <u>Molecule</u> : They are very small particles or substance specially at both structural and cellular level. These are made up of two or more atoms which are held tightly by strong chemical bonds. The four important molecules of life are proteins, carbohydrates, lipids and nucleic acids.Without any of these molecules,survival of organisms and cells is very difficult. These molecules are very important in both the ways structurally as well as functionally.
- <u>Cell </u>:Cell is the most important, structural and functional unit of life. A cell is blessed with a capacity to carry out the main functions like nutrition, excretion and respiration. Cell is the important membrane bound unit that includes fundamental molecules of life of which all living organisms are made up of. A single cell is sometimes a complete organism in itself like bacterium or yeast. The four main types of cells are Epithelial cells, nerve cells,muscle cells and connective tissue cells.
- <u>Tissue</u> : A tissue is an assembly of similar cells and their extracellular matrix belongs to the same origin which combines together and carry out a specific function. Organs are the formation of functional groups of multiple tissues.There are four main types of tissue: muscle, epithelial, connective and nervous. Each is made up of special cells which are combined together depending on their structure and function. Example of connective tissue include fat & loose connective tissue
- <u>Organ </u> : An organ is a self contained cluster or sets of tissues which perform a specialised functions in the body.Two or more organs are working together in order to perform a special body functions forming an organ system also known as body system.When organs began to shut down, person will feel drowsy and starts losing consciousness. When the heart and lungs stop working body also dies. Heart rate changes. Pulse becomes fast or irregular.
- <u>Organ System:</u> An organ system is a set/ cluster of organs which are working together to perform a certain function in the body of an organism.The 11 organ systems of the body are integumentary, muscular, nervous, circulatory, lymphatic, respiratory, endocrine, urinary, reproductive and digestive
- <u>Organism</u>: It is a creature like plant, animal or single cellular life form in comparison to a living creature. They reacts to stimuli, reproduce grow and also play a main role in homeostasis. It can be virus, bacteria, protist, fungi or animal.
