Food webs to make
Aim
To know how feeding can be out into levels and how these levels can join each other
Look at this
Consider this...
Considering the food web before as an example, what would happen if the population of slugs decreased?
Slugs, rabbits and insects all eat grass. If there were fewer slugs there would be more grass for the rabbits and insects. With more food the populations of rabbits and insects would increase. However, the thrushes would have to eat more insects to maintain their population, so it is also possible that the population of insects could decrease. This is turn may reduce the populations of voles and frogs.
Next
Explain what happens to ENERgy at each feeding level of a food chain...does it increase or DECREASE?
Starter
10. African lions are the most social of all big cats and live together in groups or “prides.” A pride consists of about 15 lions.

9. Male lions defend the pride’s territory while females do most of the hunting. Despite this, the males eat first.

8. These majestic cats are threatened by habitat loss. The lion is listed as vulnerable on the IUCN Red List of Threatened Species.

7. The lion was once found throughout Africa, Asia and Europe but now exists only in Africa with one exception. The last remaining Asiatic lions are found in Sasan-Gir National Park in India, which was primarily created to protect the species. Currently, there are approximately 350-400 lions in the park.

6. A lion’s roar can be heard from as far as 5 miles away.

5. A lion can run for short distances at 50 mph and leap as far as 36 feet.

4. Even though the lion is sometimes referred to as the “king of the jungle,” it actually only lives in grasslands and plains. The expression may have come from an incorrect association between Africa and jungles or may refer to a less literal meaning of the word jungle.

3. A good gauge of a male lion’s age is the darkness of his mane. The darker the mane, the older the lion.

2. A lion’s heels don’t touch the ground when it walks.

1. A lion may sleep up to 20 hours a day.
Food webs
A food web is simply a number of food chains joined together. It shows how the loss of one organism has an effect of other organisms in the food web. This is called the interdependence of living things.
Outcomes
Slugs, rabbits and insects all eat grass. If there were fewer slugs there would be more grass for the rabbits and insects. With more food the populations of rabbits and insects would increase. However, the thrushes would have to eat more insects to maintain their population, so it is also possible that the population of insects could decrease. This is turn may reduce the populations of voles and frogs.
