Ecology Biology Notes GCE Study Buddy Ecology ● Ecology is the study of interactions among organisms‚ and between organisms and the physical and chemical factors making up their external environment ● Ecologists study both the non-living (abiotic) or physical environment‚ and the living (biotic) environment. Physical environment ● Amount of light ○ Light intensity affects the distribution and growth of both plants and animals ● Amount of water ○ Xerophytes are plants which can

The disappearance of chairs signals the extinction of that species. Students learn how the extinction of species affects others in the food web. Grouping and Group Work: Student will form groups of two or three and discuss important details‚ concepts‚ and main ideas presented in the Musical Chairs session. They

For example‚ some antibiotics need to be taken with food and others should be taken on an empty stomach. If you do not take your antibiotics in the right way it will affect their absorption (how much gets into the body)‚ and therefore they may not work as well. So‚ follow the instructions as given by

The algae shut down fishing for crabs in most of California. This algae is also affecting sea lion babies. The problem is caused by warm ocean water. Their food source comes from cold water‚ but when the water is warm there is not enough food for mother sea lions. Mother sea lions cannot make milk without food. The babies are hungry and are super thin. The experts biggest worry is pregnant mothers since are more vulnerable to the illness because they consume more fish while pregnant

During the investigation‚ ruler and camera were used to collect data and pictures. Also‚ three tables‚ a food chain‚ and a food web were drawn to clearly illustrate the findings. In the third part‚ the classifications of the five species found in the quadrat area were listed in tables‚ and the abiotic variables‚ such as air‚ water‚ and soil‚ were analysed with their

DISCOVERY FILE: Food Chains and Food Webs All animals need energy to run‚ breathe‚ and hunt‚ and they get this energy by consuming food. Think about what you ate today: that is helping you walk‚ think‚ and read! Food chains and food webs are similar to each other‚ but they are not the same. We will explore the differences here. A food chain shows a single‚ connected path of energy flow through an ecosystem. Some animals only eat plants while some animals eat other animals. A food chain shows the
