Animals cannot effectively digest trees because trees contain a high amount of cellulose, a complex carbohydrate that requires specialized enzymes to break down. Most animals lack the necessary enzymes to efficiently break down cellulose, making it difficult for them to extract nutrients from trees. Additionally, the cell walls of trees are tough and rigid, further hindering digestion. As a result, animals that primarily consume trees, such as koalas and certain insects, have evolved specialized digestive systems to cope with these challenges. **
