HABITAT & NICHE

Difference between habitat and niche - ecology

Learn how the habitat and niche are different but also very important for a healthy environment.

A habitat is an ecological area where a plant or animal lives. It may be an island, a tree, or maybe under a rock. The habitat is where an individual can find food, shelter, protection and mates.

A niche is a role or position that an individual has in its environment. A niche may also involve what the individual eats, how it interacts with other living things, and also how it interacts with the nonliving factors. Without ecological niches, there would be less biodiversity, and the ecosystem would not be in balance.

SMELL & TASTE

Smell and Taste

Hank resists the urge to devour a slice of pizza so that he can walk you through the way we experience our major special senses.

Coronavirus: why might we lose our sense of smell and taste?

In this video Peter Brennan, from the University of Bristol, tells us about two possible reasons why losing our sense of smell and taste might be a symptom of COVID-19

SIMPLE MACHINES

This is an interesting compilation of simple machines. These simple machines use the fundamental law of forces and mechanics to carry out very simple movements. These in turn can be used to create machines that we see around us in our everyday lives. Pulley is a simple machine and comprises of a wheel on a fixed axle, with a groove along the edges to guide a rope or cable. The lever is one of the most basic forms of a machine. They help us lift loads with lesser effort. Even though this looks simple there are many things going on in order to lift the object easily. An inclined plane is a ramp that assists moving heavy objects up and down heights. It is a plane surface set at an angle, other than a right angle, against a horizontal surface. A screw is one of the most commonly used mechanical devices in the world. It is machine that converts rotational motion into linear motion. The wedge is the active twin of the inclined plane and one of the six classical simple machines. Unlike an inclined plane, which is stationary, a wedge does useful work by moving.

INVASIVE SPECIES

The basics
What are Invasive Species? An invasive species is one that is not native and whose introduction causes harm, or is likely to cause harm to Michigan's economy, environment, or human health.

The threat of invasive species.
An invasive species can be anything from plant, animal or fungus that is introduced to a non-native habitat and has a tendency to spread to a degree that causes damage throughout the environment, human health or economy.

HEARING & EQUILIBRIUM

Have you ever had the misfortune of experiencing what it's like when you sense of balance is disturbed by sneezing too hard? Watch the video and learn why this happen.

VERTEBRATES

Today we’re going to look at vertebrate animals. As you know, we can classify animals in various ways, depending on the characteristics we look at.

What is an ecosytem?

In this video you'll learn all about ecosystems and how energy is transferred between organisms living together it the same environment.

Adaptations to the enviroment

What Is Adaptation? 

Learn about how organisms adapt to their habitats. "Adapting and Living Together" within the Ecology and Environment topic for school level biology.

More explanations and examples of different types of organism adaptations, including: structural/physical adaptations, behavioural adaptations and physiological adaptations
