Look at these ecosystems. Which living things are plants? Which living things are vertebrate animals? Which living things are invertebrate animals?

Cells All living things are made up of cells. The smallest are so small you can only see them with a microscope. Different cells have different functions. Most living things are made up of many types of different cells but some, like bacteria, have just one cell.

Animal kingdom: vertebrates How do animals breathe? Mammals Birds Fish Reptiles Amphibians

Both with LUNGS and GILLS Animal kingdom: vertebrates How do animals breathe? With LUNGS With GILLS Mammals Birds Fish Both with LUNGS and GILLS Reptiles Amphibians Animals take oxygen from the air with LUNGS and from the water with GILLS.

Animal kingdom: vertebrates How do animals reproduce?     Mammals are viviparous. The others are oviparous. Some animals are born directly from their mother: VIVIPAROUS. Some others lay eggs: OVIPAROUS.

Animal kingdom: vertebrates What do animals eat? Some animals are carnivores, some are herbivores and others are omnivores. carnivores herbivores omnivores FOOD CHAINS Consumer (herbivore) Consumer (carnivore) producer decomposer

Plant kingdom How do plants reproduce? Some plants have sexual reproduction: pollen goes from the stamen to the pistil of the same plant or a different one. Some plants have asexual reproduction: there are no flowers or fertilisation.

Insect pollination Wind pollination Self-pollination Some plants have asexual reproduction: there are no flowers or fertilisation. Runners Tubers Both sexual and asexual

Plant Kingdom Why is photosynthesis imortant? OXYGEN = LIFE PLANTS = OXYGEN PLANTS = LIFE! Every animal needs oxygen to live. Plants produce oxygen and consume carbon dioxide.

Plants and animals living together animals from the same species  POPULATION different populations in one place  COMMUNITY the place they live  HABITAT habitat + community = ECOSYSTEM

How can you look after living things? We shouldn’t climb trees, pick up flowers, remove animals from their habitats, make fires in the forest or touch wild animals. We should feed birds in the winter.
