This presentation is to enable students understand the cyclic nature of nutrients in the environment. It is for year 10 (SS 1) students. it comprises of Carbon cycle, Oxygen cycle, Water cycle and Nitrogen cycle.
An Aquatic Ecosystem is an ecosystem in a body of water. An Estuarine habitat is a dynamic ecosystem having a connection to the open sea through which the sea water enters with the rhythm of the tides.
The presentation will be useful for both teachers and student in teaching and learning Cellular respiration. It is best for ages 14-16 years.
At the end of the lesson the students will be able to:
Define cellular respiration
Define aerobic respiration
Explain Krebs Cycle
For Year Ten Biology students, who needs to learn about microorganisms around us and the easiest way to culture.
Microorganisms around us
Methods of culturing
Identification and Differentiation of Microorganisms
Types of Culture Medium
Movement in and out of the cell
Diffusion - definition, process, significance, and importance
Osmosis - definition, process, experiment with living cells
Plasmolysis - definition and process
Heamolysis - definition and Process
The nature of the process and of the specialized structures developed for waste disposal vary greatly with the size and complexity of the organism.
Excretion is a general term referring to the separation and throwing off of waste materials or toxic substances from the cells
This shows excretion in Lower Organisms
“Transport system, thus refers to the movement of products of metabolic activities around a living organism”
This is a presentation Explaining why transport system is necessary in Living Organism, detailing and describing mechanism of transportation in living organisms
Although all heterotrophs feed on other organisms their method of feeding differs based on whether they are holozoic which includes carnivorous plants, parasitic organisms and saprophytic organisms, and the type of food that the organism feeds on.
Marine habitat is habitat that support marine life. Marine life depends in some way on the saltiness of water that is in the sea (the term marine comes from the Latin mare, meaning sea or ocean). A habitat is an ecological or environmental area inhabited by one or more living species. The marine environment supports many kinds of these habitats.
